My talon TSi is stuttering

[Esmith]

I have an automatic 93 talon tsi awd that is completely stock. I started having a problem a while ago. The best way I can explain it is, the car stutters when idling. When I first start it, it almost dies, it usually idles around 1500 rpm right after I start it but now it starts out around 1000 rpm but dips down to 500 rpm. I have replaced the fuel filter because I thought it was the gas i got but now it keeps doing it. If I let it warm up completely it does not do this anymore. If I try and drive it before it gets to peak temp, it hesitates and stutters even worse. I have been searching the other threads but the ones that I found did not help.

What do the plugs look like and what is their gap? How long has it been since the plugs and/or wires have been replaced? There can be other things, but this is the first thing I would look at.

This is where i would start Also may wanna check for vacuum leaks as well, because those will give you some idle issues.

+2 on checking plugs, wires and for vacuum leaks...something else i would do is clean your throttle body...keep us posted

Thanks guys, now I have a starting point. I am not sure how old the wires are, the plugs are around 5 yrs old. So I guess its time to replace both. As for the vacuum seals, I will check those asap.

Yeah, I would definitely start by replacing the plugs and wires. Make sure you get NGK BPR6ES plugs gapped to .028" as they will work the best for you. Good luck!

The stock plugs are BPR6ES gaped at .28. Always go with NGK.

Don't buy into the iridium bullshit, they are TERRIBLE for turbocharged cars.

I would also check the coolant temperature sensor.

it can be as simple as havin an air bubble in your cooling system. top it off. May also be a boost leak. i found 8 in mine;i had to zip tie a bunch of vacuum hoses.

When I removed the wire on the last one the end of the wire stayed attached to the spark plug, It was horribly corroded. I was kind of surprised because the cables themselves looked as new as the ones I bought. The spark plugs were not in that bad of condition but I replaced them anyway.
