So I found out my car has the low idle and bumps a little shifting (automatic). but only when the engine compartment is warm. i thought it was when the car ran fr a few minutes and a loop opened. but now its only when the engine is warm. any ideas? its a 94 gxe automatic. fuel injecters are all good.

 

Do you feel any misses at all when the car is cold? Even just the slightest? Mine would do the same thing, ran fine cold and terrible when warm. It would hesitate off the line and "burp" during periods when I was giving a small amount of gas. However, if when the car was cold, it would give the slightest of symptoms every once in a while. Ended up being ignition coils.

 

thats exactly what my car does. how much are they and how many are they. easy to fix myself?

 

I am not sure on yours, but mine were about 90 a pop for each. I had six total. I think (this is a big guess on my part here) your car only has one and it would be about 240 from a place like here that sells genuine nissan parts pretty cheap. You can buy it from other places as well that are not genuine parts for a much better price. Other guys here would have more info on that. Also, others here would know if your car needs 1 or 6 of them, but I am pretty sure it is just one.

The job is pretty easy now that I know how to do it, in fact too easy for what I paid someone to do it. Live and learn. But yours may be different since I have the SE model, not the GXE.

Also, before going and buying a new coil it may be worth your while to explore other less expensive options like cleaning the IAC and seeing what happens. Again, others would have good advice on this.

 

his car is a GXE according to his profile.
he needs only 1 coil if it's bad.

how old are the cap,rotor, wires, o2 sensor, plugs, etc...?

 

distributer and wires / plugs are all redone about 10 months ago. but they ran for 8 months on 1 bad injecter. 02 senser i have no clue. but i thought that wouldnt be effected if the car was warm or cold.

 

o2 sensor only effects car once it is warm. If you are having the problems before the car is warm also, then o2 sensor would not be the culprit.
