need help on rough idle...did a bunch of tests...

[killer5.0]

okay so i took it to my mechanic and he tested the TPS, AIC, ran the codes ...everything came back good...he had one code that was for a "flapper" on the stock airbox control i guess but said that since i have an aftermarket its not there and shouldnt affect it...he tuned the idle up a little which helps but its not a permanent fix he said...here is my list of mods and where should i go next? do i need a custom chip?

BBK headers, h-pipe to borla dumps (b4 rear axle)
BBK 70mm Throttle Body
BBK 70mm MAF
BBK CAI (fendermount)
3:73 gears
F303 cam
GT40 Upper and lower intake manifold
BBK FP regulator (at 38lbs at idle)
19lb injectors
200a alternator

thanks

Find out what the actual code was.

If the idle itself is rough, like it misses, run a cylinder balance test.

Good luck.

ill find out the code...definately isn't missing.

 

[killer5.0]

codes thrown were...

21 (because it wasnt at operating temp at first but then he redid it with it at temp)

then it pulled
94 thermactor
44 thermactor...just want to verify what these codes are..

Thermacore is the secondary air system (i.e. your smog pump and emissions controls). Are you running your smog pump still?

 

[killer5.0]

the smog pump is currently hooked up but throwing air into the engine bay b/c i need to buy a shorter belt still...but i removed all the hardlines and vaccuum lines and plugged everything.

If the smog pump is not dumping air into the exhaust system, then codes 94 and 44 will show.

If the smog pump is not dumping air into the exhaust system, then codes 94 and 44 will show.

so nothing to worry about then...it cant affect performance correct?

Your fine, no different then any other Smog delete on these cars.
