hi this is my first post, i usualy search and find the answeres to my questions. well any way i just got this 89 240sx hatch with a red top sr in it. the engine kinda runs like crap you have to slowley get into the throtel and only hold it half way or it bogs and is really slow, it doesnt smoke so i dont think its running to rich. anyway i pulled the engine codes and got a 11 and 12 which is the cam angle sensor and the mass. i was wanting to see if you guys could help me out as with what to check and how i can check these problems.

thanks jason

 

well not sure about cam anlge sensor but MAF will make your engine bog and run like **** so first check if the plug is on tight take it off put it back on if that dosnt fix it, it might need a new MAF

 

yeah......it must be a sensor.......

 

whats the numbers on your mafs?

and its likely to have the CAS go bad
