TurboTobz Posted April 11, 2013 Share Posted April 11, 2013 (edited) Maybe insignificant, yesterday I got two backfires when going slow, thought that's a bit odd, barely does it but has done it before under similar conditions.Today I went to leave some traffic lights and it started to die out but drove fine, next set of traffic lights same thing so went home and had a little try pulling onto my drive it does it also which is slightly uphill.I could hear it kinda backfiring or missin on tickover through the exhaust, so I had a look under the bonnet I felt my coolant hoses they felt pretty hard but it was hard to check thoroughly as they were so hot!Took the rad cap off with a towel and lost a load of coolant.I pulled off the ht leads one by one, they all made the engine run like crap so my thoughts are possibly coil? Or fuelling?Watching my wideband as I was trying to pull away and it seemed to head towards the leaner scale.Under boost it didn't miss, it's not seemed to lose any coolant, temperature stayed towards 1/4, no real white smoke, no petrol smell in coolant.What should I check my first thoughts are maybe injector fuel pump fuel filter coil.As for the hoses thermostat, hg at worst, or maybe I had an air lock? If anyone can tip me I'd be really thankful cheers Edited May 8, 2013 by TurboTobz Quote Link to post Share on other sites
Danza V Posted April 12, 2013 Share Posted April 12, 2013 Pulling the leads off is a good sign if they all do it , it's if I does nothing when you pull em off.Does it idle ok? Have you also checked the oil cap or bottle for "mayo"? Rad hoses should fairly firm when engines running but not solid otherwise gases are getting into the system which can only mean hg me thinks.Checked for any va c leaks at all?Others maybe able to help more Quote Link to post Share on other sites
TurboTobz Posted April 12, 2013 Author Share Posted April 12, 2013 Don't think there's vac leaks did have a general check, did check for mayo not even a slight bit on there hmmm I think ill try diagnostics I've read water temp sensor and lamda can give similar faults although my widebands reading usual readings idle and cruise, idles a little high but has been for a while Quote Link to post Share on other sites
Weyro Posted April 12, 2013 Share Posted April 12, 2013 try taking the distributor cap off and cleaning everything, including the leads Quote Link to post Share on other sites
akyakapotter Posted April 12, 2013 Share Posted April 12, 2013 Hard hoses you mean coolant hoses ?? If they are solid I'm afraid it's hg on its way out mate. mine done this drove fine no overheating sod all just threw coolant out when I took the cap off because c02 getting into the system get it sorted before it gets any worse. mine currently at td waiting for it to be fixed drove sweet as a nut all the way up there which sucks as I know it's gone as had it sniff tested.

You sprang to mind actually when it happened, I've been looking at your thread. If it is head gasket the engines coming out and not going in until I have a new clutch, Athena hg, and my forged rods pistons and arp bolt set. Shame I'm broke lol ah well got a little money saved by.try taking the distributor cap off and cleaning everything, including the leadsWill give this a shot .

akyakapotter Posted April 12, 2013 Share Posted April 12, 2013 Get it sniff tested mate takes a garage about 30s an gives you a 100% if its HG or not Quote Link to post Share on other sites
TurboTobz Posted April 12, 2013 Author Share Posted April 12, 2013 Get it sniff tested mate takes a garage about 30s an gives you a 100% if its HG or not I'll get my old man or mate to grab me what I need from work lol, cheers buddy Quote Link to post Share on other sites
TurboTobz Posted April 12, 2013 Author Share Posted April 12, 2013 Well I just need the fluid, got the tester in my toolbox lol Quote Link to post Share on other sites
TurboTobz Posted April 13, 2013 Author Share Posted April 13, 2013 Diagnostic test showed a continuous flash series that was never ending I sure felt like a prick once it exceeded 50 showing no sign of stopping LOL Quote Link to post Share on other sites
raffa_mk Posted April 13, 2013 Share Posted April 13, 2013 Might be coolent temp sensor. Stick in a new one as see what difference it makes Quote Link to post Share on other sites
TurboTobz Posted April 15, 2013 Author Share Posted April 15, 2013 ^ one of my thoughts that, I do have one spare so I will have to try it thanks. Not been able to try a lot all my tools are in my garage a town away! Quote Link to post Share on other sites
TurboTobz Posted May 7, 2013 Author Share Posted May 7, 2013 So sniff test said not head gasket, I'll be trying a thermo and water temp sensor and plugs that I have laying about, I think possibly a coil/dizzy/igniter maybe a good thing to try, any other suggestions of things I need to do? I doubt it's leads as they're pretty new, and king leads under 3 months old. Quote Link to post Share on other sites
TurboTobz Posted May 7, 2013 Author Share Posted May 7, 2013 (edited) Another thing, when it was tested the rubber bulb wasn't used to draw air in, the car was running for around 4-5 mins with the tester on it. Now I asked about the rubber bulb and my mate said he's never been taught to use one at work, I've had a little google and I have seen other people saying you can just let the gasses pressurise the block tester rather than drawing it through but I just want to check is the way the test was carried out correct, before I cross head gasket out of my mind.Cheers Edited May 7, 2013 by TurboTobz Quote Link to post Share on other sites
akyakapotter Posted May 8, 2013 Share Posted May 8, 2013 When mine was tested we run it up and used the rubber squeezer to draw the air out of the system to which it turned the blue liquid to yellow telling me there was co2 in the system = HG failure Quote Link to post Share on other sites
Arnold Posted May 8, 2013 Share Posted May 8, 2013 (edited) I doubt it's leads as they're pretty new, and king leads under 3 months old. One thing I was always taught is that just because something is new, doesn't mean it isn't the problem . I've got a miss fire issue too since having my HG replaced and it's proving to be a pain to troubleshoot. Edited May 8, 2013 by Arnold Quote Link to post Share on other sites
TurboTobz Posted May 8, 2013 Author Share Posted May 8, 2013 Well he's text me today to say it runs off rad pressure, I don't know the bloody thing ran out of petrol while we were looking over it last night damn Quote Link to post Share on other sites
Addymk2 Posted May 8, 2013 Share Posted May 8, 2013 Mine did this when one of the connections on the Dizzy was corroded... Quote Link to post Share on other sites
TurboTobz Posted May 8, 2013 Author Share Posted May 8, 2013 The contacts on the cap? Cheers Quote Link to post Share on other sites
Addymk2 Posted May 8, 2013 Share Posted May 8, 2013 The contacts on the cap? CheersYeah mate I got some of the rust removing juice and a pipe cleaner and it cleaned up alright! Can't hurt to have a look Quote Link to post Share on other sites
TurboTobz Posted May 8, 2013 Author Share Posted May 8, 2013 (edited) I have had a look I found corrosion to all 4 tips and slight indents, the king lead came out and some white dust was in there as if that has some slight corrosion. The contact on the rotor shew some corrosion and the plastic itself has a crack, anyhow I'll upload some pics. The picture of the rotor arm is after I gave it a little whipe.Could these be at fault? Gould I be replacing or cleaning them? I have another rotor arm from a head I stripped so could pop that on. Pics will be up in a moment!

Addymk2 Posted May 8, 2013 Share Posted May 8, 2013 (edited) Doesn't hurt to give them a clean up with some electrical contact cleaner etc and see if it improves, if it improves it might be worth picking up a new dizzy cap. But be sure before throwing money away then it being something else EDIT: 3rd pic down of where the leads plug in, mine were like that and I had a crack from where the previous owner decided that tightening everything up to a billion lbs was a good idea! new one arrived and they were all shiney. She's ran fine since! Edited May 8, 2013 by Addymk2 Quote Link to post Share on other sites
Gary91 Posted May 8, 2013 Share Posted May 8, 2013 I had a similar problem, turned out the points on the dizzy cap were quite worn and my king lead was rotten.I fitted new dizzy cap and rotor, leads and plugs and it ran perfectly after that.In your case I would clean up the points and see if its any better.

TurboTobz Posted May 8, 2013 Author Share Posted May 8, 2013 I have a rotor to hand, so I'll probably end up changing that but for time being I'll give them a good old clean up and try and get some bloody fuel in it and try it again, I will change the plugs when I can get over to my garage along with rotor hmm I don't feel this is the root of my troubles I was expecting it to look worse but it may just be ba contacts I'll hope and pray lol.
