okay i have an 89 camaro,i took the 2.8 out and harness had a 88 iroc tpi took harness and motor put into the 89 well it runs in nuetrual but when it gets a load on it it dies and runs like crap and stays like that till i shut it off then it's fine for a lil bit then it does it again.new fuel pump,maf sensor,tps,cts,new 350 motor,trans,fpr.it wont run on the road?it dies stalls,changed distributers did nothing,new coil nothing,some one help this is my daily driver thanks

 

no one? nobody has had this prob before?it's an auto.

 

come on people i aint rich and ive spent over 2500 so far on a car that dont run.iam out of money could it be i didnt change the dash harness?

 

Is the SES light coming on when it is running poorly? (It should come on when the engine dies.)

 

Sounds like a vaccume leak issue. Listen for hissing from somewhere. Those runners are a PITA to install and seal up. I dispize working on them

Have you taken a look at the IAC (idle air controll valve) that's what really makes it Idle correctly.

Make sure there is NO leaks in the ducting between the MAF and the throttle body.
PCV all hooked up correctly?
EGR Stuck open or vaccume hooked to it wrong causing it to open?
Sounds like somthing simple...

yea the ses is on.when running poorly i gives me a code of an ignition problem.yes i clean the iac.the maf,fuel pump,cts,imts,tps.it runs good cold til warmed up and then it wont go down the road like she's starving for gas o and i have a new fpr.or loosing fire,thanks for replying

thanks tell me if u can think of something else.

 

What ignition code is that?

 

Yea... what ignition code????? 43? other?

If it's good when cold it's somthing when it go's into "closed" Loop.

O2 hooked up? Need to look at the perameters that the computer rely's on when in closed loop then.

code 36,distributer blah blah but i got code 36.also the new fuel pump sounds horrible like louder than old one?bad pump?doa
----------
whats code 43?

 

Code 36 is MAF burn-off circuit, not ignition.

Have you put a fuel pressure gage on it?

 

no fuel pressure gauge dont have one.but the maf is new.

 

A new MAF won't affect the burn off circuit.

A fuel pressure gage is a good investment.

 

i didnt no the 88 had a burnoff where is it?

 

where is the burnoff?

 

okay i got it running good but now it has a miss/upper rpm
