Help!! Car Wont Idle
Help!! Car Wont Idle this is the only place i know where to put this bc it involves a turbo set up. i just changed the wires and now the car wont idle right. the vac. on the boost gauge starts at 20, where it should, then slowly drops down to like 10-15. this results in choppy idle and car dying. i also moved the coolant temp sensor from the front of the drivers head to the rear on the pass. if that means anything. i know that one time i forgot to plug it in and it did the same thing except it wouldnt start hardly at all. let me know if you guys have any ideas or suggestions. thanks in advance
didnt try just want to see what every one thought. would it really matter where it was at? it just makes the plugs fit a little better. i'll have to try after while. just moved so the car isnt at my new place
It could matter. If the engine can't determine the proper engine coolant temp on start-up it will have troubled delivering the appropriate fuel. I'd just switch it back. Also, it could be that those custom wires are faulty, ie. poor connections at the terminals that are crimped on, etc.
if you have auto-tap look at the ECT (water temp) if it looks normal and tracks as the car is warmed up, then thats not the problem. Other wise make sure you are getting a good connection on the plug wires.

new thought. could the reason i am having problems is the fact that i lost some coolant when i moved the sensor. and now there isnt a sufficient amount in that head to allow the sensor to read right? i have not put any more coolant into it, just didnt think i lost that much but im not sure. any thoughts to this. i was eating and this popped in my head just figured i would throw it out on the table. let me know what you guys think
Take off the radiator cap
Start the car
Let it hit operating temp (thermostat will open)
Then keep filling it up until the level holds at the radiator and the air bubbles have stopped for the most part.
That'll make sure you have the proper amount of coolant.

here is the finding:
if your coolant is too low your car wont idle. also if you move that sensor i guess you have to reset your computor to allow the car to pick it up correctly. at least that is waht i found out. put new coolant in and it still had a hard idling then unhooked the battery for a bit then allowed time for things to get settled in and it starts just fine. and ildes as well. drove it up the road to my place and it never missed a beat. later on
