Leaky Injector
|
Hmm, yes you can pull the vaccum line and see if idle changes. It could be possible you have a fuel injector issue (staying open). When was your fuel filter changed last as well?

It was changed about a month ago. Only thing thats not leading me to believe its a fuel issue is that its just rich initially. Like once its running it runs fine other than a bog around 2500 rpm and when you floor it in a high gear, which i think is due to improperly gapped plugs, forgot to gap them once i put them in. Its just once it first starts cold it wants to die unless you gas it and hot starts it wants to die unless you gas it but 2 mins later it will stay on by it self and drive fine. |

Okay so I got it fixed. Checked my tps it was out of calibration, was at .39 and should of been between .45-.55. Got that set and got a new temp sensor from the junkyard, car cuts on every time now with no gas given.
Figured it out because when i disconnected the NEW ECT, it would idle lower and when revved it would backfire out the ass which is a sure sign of too much fuel. Reconnected it and idle raised, no backfire. So if anybody has the same problem, definately check your tps and coolant temp sensor. ![]() |
