Engine Trouble i think!!

[Tha Dragon]

Hi guys,

Don't know if this happened to one of you, but i was driving to work today, all of a sudden "Check Engine Light" starts flashing and "RPM" gauge starts going up and down like crazy.

Before today if i put down a street race and after that come to a stop or at the lights it will "Idle" very low or turn off on it's own and takes time to turn back on.

can one of you guys let me know what the problem could be?

[Chris Green]

Check the throttle position sensor. Had this problem on Sunday night.

[Tha Dragon]

Is there a Chance you can send me a pic of where it is located

[Chris Green]

It's on the throttle body, if your looking down on it, it's at the back, a black square box.

[rasslenny]

on top the intake manifold there is a little circle piece of rubber its like a little cap beneath that is a screw that controls your idle.... if the screw has become loose and unscrewed it self enough the idle will be way tooo low to keep the car running it has happened to me already after a very and i mean very spirited bit of driving

its an easy fix ... flat head screw driver is all you need screw the bolt in a little and turn the car on.... then you adjust the idle the same way screwing it till its where it needs to be a little under 1000rpm on idle is where i have mine

Ok Thanks guys

gonna check it as soon as i get home

i'll keep you guys posted

[maddox710]

I had this when wire on my hks fcd came lose

[Tha Dragon]

Hi guys gonna check it out today it has gotten worse, it keeps flashing the "check engine light" and "rpm" gauge keeps acting crazy and about the "TPS" do you have a diy guide or some on how to remove and install the "TPS"

thanks in advance

guys

[Chris Green]

It really isn't hard to check mate, little black box on the back of the TB, just check the wiring for a start.

There are 3 wires in the plug that connects to the TPS.

[Tha Dragon]

Ok, but can I just remove it and put another 1 in it's place?

[Chris Green]

No, as far as I am aware the FTE ones are 'slotted' meaning they need to be adjusted. I'm not sure if there is a guide on here. To reset the TPS you need rotate it while on the butterfly pin 360 degrees anti-clockwise. - This is from memory, I remember reading about it somewhere.

But two small bolts hold it in place. If you have a strut brace, it would be easier to work with if you removed it.

[Tha Dragon]

Ok, I'm gonna try it out I have an engine in my back yard gonna take it off and put it on mine

I'll keeep u posted thanks

[Tha Dragon]

Here is a pic of the on I took off the engine I have in my yard does it look ok?

hope u can see it I'm on my galaxy

[Chris Green]

Yeah, that looks spot on mate. As I said check the wiring first.

[Chris Green]

Sound have mentioned this first. Run the self diagnostics. Bridge ports E1 & TE1 and that will give you fault codes on the dash.

Here's a guide http://www.ukstarletowners.com/topic/9295-how-2-perform-a-diagnostics-test/

[Tha Dragon]

Ok, I'll let u know

[Tha Dragon]

I did the diagnostics it flashes 34, turbo pressure signal

what do I need to do now, I replaced the "TPS" already so what now?

[Chris Green]

Don't know where to go from there mate. I don't have a clue about turbos. May be worth changing the title name.

[Tha Dragon]

Turned it on, no check engine light no nothing I'm gonna let it run idle 4 a bit wash the car and take it for a spin I'll let you know

[corofin12345]

if your rev needle is jumping its not the TPS.. reset the ECU (disconnect the battery for 5 minutes, then re connect) and go for a drive and if the EML comes on, do the diagnostic test again... its distributor related, you may of even skipped a tooth on the timing.. may be worth timing the engine when your at it

[Tha Dragon]

Before the story I just wrotethe EML never came on but I was driving 1 day and all hell broke lose, EML stared flashing, rpm needle started jumping up and down, now I need to take it for a spin tosee if it's ok

[akyakapotter]

Check your earths mate mine went mad the other day turned out the earth in the drivers kick panel had come loose.

[Tha Dragon]

i just took the car for a drive, with A/C off it won't idle for long but as soon as i put A/C on it will stay idle like a charm

So i went and turn the screw a bit it idles now with A/C off and A/C on but when i turn the A/C on it will idle to high i think it will almost get to the 2000rpm

Can you guys tell me what i need to the or what the problem is?

[Tha Dragon]

Hi Guys,

The Car is still having the same problem i replaced the TPS, i checked earth, the just doesn't wanna stay idle isn't there anything else that i can do?
