Question about 1987 Chevrolet Camaro

1 Answer

87 Iroc (305 TPI) runs rough, lopes and lacks...

I have a 87 Iroc 305 Tuned Port Injection that is having some nasty issues. The engine starts without issues, however it will attempt to die at idle if you do not keep you're foot on the gas. It also smells like it is running really rich. At highway speeds, it seems fine, but driving around the city is horrible. While driving through parking lots or at a stop sign/light it lopes and attempts to die. I've replaced the MAF sensor, plugs (which the gap was verified), plug wires, distributor button and cap, PCV valve, & air filters. I just found the bypass wire and will be checking timing tomorrow; but other than that, I'm running out of ideas. Can anyone help?

    Try checking to see if the cadalydic converter is plugged, I had similar issues with mine and replaced everything we could think of and turned out it was so plugged it was no wonder the car would run at all.

'87 Iroc fuel port injection. Car won't start. Can't hear fuel pump running when ignition is turned on. Starter turns but engine will not start. Where is fuel pump located on gas tank?


The pump is in the tank. Empty the tank, disconnect the filler and vent tubes, and remove the straps that hold it under the car. Take the strap bolts off the rear end and the front should just slide out. Have a jack ready to help lower and roll out of the way.

1988 iroc-z 350 tpi - runs poorly when hot (190-200degrees)


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.

Thanks - Tech101
