Alright my transmission, driver side axle, and clutch were just replaced. I don't know if that makes a difference or not but I'm sure it does since the problem has just came up after those were replaced. Ok usually when I start the car it runs fine and idles great, but after a little while of driving in fifth gear or fourth gear the check engine light pops up and then when I come to a stop light and put it in neutral and let off the clutch it starts reving and trying differen't idle's. Got any ideas what I should check or what the problem is?

 

first of all i'd get the code
can be a few differnt things

 

How do I get the code?

 

look at ECU count blinks return with # we shall help then

 

I feel real stupid right now, but how do I get to the ECU to count the blinks and in order to count the blinks do I just start the car and look to see how many blinks it makes? I mean do I have to pull up carpet or anything to get to the ECU? I've just never done it before.

 

Pull the passenger carpet up, there will be a little glass window so you can see the ecu. turn the key, watch for blinks.
