need help diagnosing problem with 1990 eclipse gst


first the car barely holds idle with , car is running a little bit rough

but the main part is the car is not letting rev past 3.5k rpm somtimes 4k rpm

it seems like its hitting the rev limiter

under full throttle it just sounds like its hitting rev limiter.

like a wah wah wha wha sound.

i drove the car for a little bit and at some points in the rpm, the car feels a little healthy

its not the engine, but soemthing electrical

just change the transistor, still same thing. not ecu as i pulled it out all conections are fine and nothing is blown or disconnected inside it

so i narrowed down to the MAF or maybe cam angle sensor

what do you guys think?

the car does nto really drive so i can take it to a shop, can anybody come and take a look?

all help would be appreciated


BTW if i do need a MAF does anybody have one for sale?

which mitsubishis MAFS are compatible?
