hey guys my b18 has lost a lot of power lately and has a small and suddle idle surge when its just warming up. and it seems like it is still pulling good at half throttle like it use to but when i go ***** out its sluggish and thoughts of what it is let me know the motor is in a eg hatch

 

Time for a tune up

 

already did oil change cap and rotor plugs pug wires fuel filter

 

Have you lashed your valves. Are you burning oil. Have you changed your coolant. cleaned your iacv. cleaned your fitv. compression test

 

not burning oil. i am thinking i have a sensor out

 

check coolant for oil...

 

nope. i have checked all the common stuff like that i more looking towards computer related like could my map sensor do that

 

how about replace your fuel filter/air filter?

 

Have you checked the ignition timing with a timing gun? Is the CEL on?

 

Cel was on when I got the car. So I don't know if it threw another code. How do u check it. I want to time it and figure what code it is throwing

 

Click here to learn how to pull the CEL codes. Use a timing gun to check the ignition timing.

 

ya check timing and do a compression test, timing belt could've skipped

 

everyone blurts out all these crazy answers. check the code first
