Running Rich

Well there is something wrong with my car. When warmed up the car has rough idle. When driving and it reaches between 3-4k RPM. the car seems like it has a miss.

I have changed the following
O2 Sensor
cap
rotor
wired
coolant temp sensor
plugs



I was thinking maybe i have bad injectors? no idea
I took a pic of my spark plugs and plug 2 and 4 dont look good at all. these were brand new plugs about 2k ago. Any suggestion would help.

Thanks
Pummy

try cleaning out your ICV(idle control Valve) just spray some brake kleen in there and it should be all set.

had a similar problem.
