Mr. Chem Posted November 4, 2014 Share Posted November 4, 2014 Hi all,I'm having some issues with my glanza. I've been finding that around 3500-4000 revs it hesitates at full throttle and boost. If I back up to 0.5bar it starts pulling again.Low revs and high revs are fine.The car is running 1bar on a ct9 on a jam ECU.I've only noticed it doing this when I upped boost from 0.8 to 1 bar.So far I've changed plugs, dizzie cap and rotor arm. The leads are Ngk blues about a year old and still at a good resistance level.I have looked at the coil, cleaned up the base plate and fitted another earth to it.No fault codes stored. I've tried unplugging the lambda sensorI don't know if it's related, as it's always done this, but after a hot start the engine revs very low for a few minutes.Thanks Quote Link to post Share on other sites
Gainzy Posted November 4, 2014 Share Posted November 4, 2014 Are you running an aftermarket fpr Quote Link to post Share on other sites
Mr. Chem Posted November 4, 2014 Author Share Posted November 4, 2014 Standard fpr Quote Link to post Share on other sites
mikey4410 Posted November 4, 2014 Share Posted November 4, 2014 what are your afrs at full boost ?? Quote Link to post Share on other sites
Gainzy Posted November 4, 2014 Share Posted November 4, 2014 You might aswell change the leads could try cleaning the icv and tps it was happening to my mates V recently I have just txt him if he got sorted. Quote Link to post Share on other sites
Mr. Chem Posted November 5, 2014 Author Share Posted November 5, 2014 No wide band I'm afraid Budget is seriously limited Quote Link to post Share on other sites
funny onion Posted November 5, 2014 Share Posted November 5, 2014 I'd say it's running lean if it was ok at 0.8 but not at 1 bar and nothing else has changed. get a rrfpr with gauge on it and richen it up slightly. Hard to do without a wideband though, you need to be careful not to have it too rich or you'll suffer from borewash. But if it is running lean that's also not good for the engine...

Gainzy Posted November 5, 2014 Share Posted November 5, 2014 My mate got back in touch before, he changed his leads so it's worth a shot I would. Quote Link to post Share on other sites
Socks Posted November 5, 2014 Share Posted November 5, 2014 What pump is in it? Quote Link to post Share on other sites
TrisK Posted November 5, 2014 Share Posted November 5, 2014 I would try leads. I would also try gapping your plugs down slightly. Quote Link to post Share on other sites
mikey4410 Posted November 5, 2014 Share Posted November 5, 2014 thats a good point from socks there.what he said Quote Link to post Share on other sites
Mr. Chem Posted November 5, 2014 Author Share Posted November 5, 2014 Plugs are gapped to 0.8mm.I guess I'll have to try a different set of leads thenHopefully that works It's running a tuning developments 255lph pump Quote Link to post Share on other sites

A Walbro would be a better spend of money imo... To my it sounds like fueling. If you've serviced the ignition system... Quote Link to post Share on other sites
Mr. Chem Posted November 5, 2014 Author Share Posted November 5, 2014 Well that's irritating. I'll see about a pump then. Seems strange it pulls fine at higher revs though Quote Link to post Share on other sites
Gainzy Posted November 5, 2014 Share Posted November 5, 2014 I would change the leads first my non branded fuel pump has ran 4 years no problem Quote Link to post Share on other sites
Socks Posted November 5, 2014 Share Posted November 5, 2014 I would change the leads first my non branded fuel pump has ran 4 years no problem Yeh I know of a few that have lasted too. Hit or miss I guess... Magnecores are a wise purchase anyways tbh! Quote Link to post Share on other sites
Vturbo Posted November 6, 2014 Share Posted November 6, 2014 My TD fuel pump has been going for about 3 years now Quote Link to post Share on other sites
Mr. Chem Posted November 8, 2014 Author Share Posted November 8, 2014 New symptom - smoke during the stutter.Stutter is worse under load (4th and fifth uphill) Smoke appears white I think. It's not much and there is none on idle, just when it stutters. Quote Link to post Share on other sites

It's not much and there is none on idle, just when it stutters.They say white is water, is your fan kicking in when warmed right up? Check your water levels just incase Quote Link to post Share on other sites
Mr. Chem Posted November 8, 2014 Author Share Posted November 8, 2014 Not lost a drop. Fan works perfect.White can also be over or under fuel Quote Link to post Share on other sites
Gainzy Posted November 8, 2014 Share Posted November 8, 2014 I would buy some ht leads and go from there I still reckon your not getting a good spark Quote Link to post Share on other sites
Stu Posted November 9, 2014 Share Posted November 9, 2014 Know anyone with a wideband? Quote Link to post Share on other sites
