Got any Advice on my 350 TPI??
So I bought an 1987 Iroc-Z Camaro with a 350 TPI. It has a fair amount of work done to it here and there, but its a Dog. and It likes to stall out and rev really low when sitting at a light. Its an auto with a 700R tranny.
Modifications:
Balanced and Blueprinted Injectors
Modified Mass Air flow sensor
Air Foil
8mm special fit plug wires
Adjustable Fuel Pressure Regulator
Throttle Body Cover plate
Ported and Polished plenum, Runners and intake ports
EGR valve
Oxygen Sensor
Throttle Position Sensor
Idle Air control valve
Manifold air temp sensor
and all gaskets seals and O rings have been replaced.
K&N filters with cut out air boxes
ECM/ ADS strip chip
160 Thermostat
Rebuilt distributor.
Im not sure why it isnt running to full potential, Ive cleaned the MAF sensor, filters and Throttle body hoping that would help it, because it sat for 6 years. all the work was done in 1996-97. so Im not very familiar with the car. anyone got some Ideas as to why its so dull?

Possibly Idle air control. Mine did the same thing and turned out to be that.

Bad gas? How old is the gas in the tank? Also, have you checked the fuel pressure? What is modified on the MAF sensor? Do you have access to a scanner?
Whenever I get a TPi car, it runs like crap mostly due to the previous owner having it sit so long, the gas goes bad. After that, I always do a complete tune up, to eliminate that.
Are there any SES lights?

Re: Got any Advice on my 350 TPI??
Sorry to bring this back from the grave, But Just an update, About a year ago I was pulling out of my driveway and it back fired real bad. now it has a ticking sound and I havent looked at it since.. Been busy with a new job and such. As soon as the snow leaves im going to tackle it. Ive done alot of research on this motor in the past couple years. It had a bad battery, Im thinkin it made the Computer all screwy and threw my timing off alittle bit. It was also running alittle rich before It happend. So As a result I think I may have bent a pushrod in the passenger side head.. Now to clear all that AIR stuff and coolant lines out so I can get at it haha
