Question about Chevrolet Camaro
First, did you check the fuel filter to see if it was clogged (cheap fix to replace it if you haven't recently)? Second, there's a fuel pressure regulator at the back of the tpi rail (back by the distributor). This has a diaphragm and spring in it. If the diaphragm leaks, the fuel pressure will be erratic. If you're going to check the diaphragm, I'd recommend installing an adjustable fuel pressure regulator where the stock (non-adjustable) fuel pressure regulator is at. The rail also has a bleed down circuit which will drop the fuel pressure once the vehicle is shut off. Third: the in-tank fuel pump could be on the way out.

Does it run poor at full throttle or between quarter and half throttle? Does it hessitate? If it does the EGR valve may be worn out. I had an 87 transam with TPI and was having problems with it stumbling and hesitating when it was warmed up. If the car starts hard and you have these problems then the issue may be low fuel pressure. Hook a guage up to the fuel rail and make sure you are getting pressure. If you are only getting a few pounds of pressure it may be the fuel pump or fuel pressure regulator. Good luck and if you thought this information was helpful please rate it when you get a chance.

you can run this motor carburated if you want by purchasing an after market conversion intake and carburator setup. if you want to leave it fuel injected you will need to swap wiring harnes and everything, computers and sensors you will have to run manual guages for the temp sensors and oil pressure guage and alternator due to your speedo being unable to accept them.

Okay, #1 is marked on the distributor so in clockwise order: 1-8-4-3-6-5-7-2
Hope this helps,

If it is fuel injected,the fuel pressure regulator is most likely the problem,if it is carbureted the mc solenoid could be the problem,or carburetor needs rebuilding.
