CEL with Code 1 & 2

[jt6117]

Guys i have CEL with code 1 & 2 for quite a while and still cant get rid of it after changing O2 sensor, spark plug, ignition coil, fuel filter, clean up throttle body, EGV & injector. Wondering what else can caused the code? It only come on when i part throttle going up a slope or trying to accelerate without kicking down. I have Code 36 as well that is because i have removed the TCS. Anyone experience this before? Please advise me as it is very annoying to see the CEL light on every single time.

What does "cleanup injector" mean? What did you do for that? If you have not I would send your fuel injectors out to RC Engineering to be cleaned and flow tested.

I sent it to a workshop to be cleaned and they just used the ultrasonic bath to clean it. No flow testing tho. Do you think I should send it for flow testing?

I can only say that I have had the issue you describe and that cured it for good.

HTH,
