Engine troubles

[I Am Chris]

Ive searched for an answer here (along with a few other sites) and I have not seen anything that stands out as an answer for me. My KADE seems to have a few problems that I can not sort out. Lets see... I have an irratic idle(even worse at operating temp), car back fires only at operating temp when I rev it up around 2-2.5k, definitely smells like its running rich. Ive checked out the maf, searched drasticly for vaccum leaks with none to be found, & adjusted the iacv screw. I ran out of light to test anything else out today. I know I have a small exhaust leak at the test pipe and not sure if it matters but I have no egr and the hole in the manifold is plugged for the egr.

So Any and all ideas are wanted so give me your input no matter how small.

dam my kade is doing something like that, it also idle a little funny when start up, and sometime when hot, i was told to clean out my fuel system. I think you should try that.
hope that help, good luck.

i had the same problem turns out two fuel injectors were from a different car and did not work. pull each out when car is on if it changes it fine if not the injector does not work.just to be safe

Yea ive done that they all work. I think number 4 might be sticking up. And i forgot my oil smells really strongly of gas

[jrodasjr]

Leaky Injector?

[I Am Chris]

injector is my suspicion, im pulling the fuel rail tomorrow and checking it out. With the plugs pulled I cranked the motor for a second and the fourth cylinder has a much stronger odor of gas then any other by far. Im thinking maybe I have a sticking injector. The problem is only present at idle, the car drive just fine with no hesitation so thats another reason im suspecting the injector but I could be wrong

Okay well im not sure if this will make a difference but I noticed today that the removal of the tps has no effect of how the motor runs, not sure if disconnecting it will only matter under WOT or if it should have an effect no matter what?
