Hey guys,

I have a 1987 IROC z-28, with the 305 TPI automatic transmission. The other day, i was driving home, and I noticed my car was kinda driving a little weird... so I pulled off to the side of the road, and as soon as i let off the gas, the car stopped. I looked at the engine and didn't see anything out of the ordinary, but after trying to start it a few times, I smelled gasoline. Found out that it's leaking out of the throttle body where the intake is attached. It seems as though there is a lot of gas just kind of slowly leaking out.. but when i press the gas, it opens the throttle and gas pours out.

Have any of y'all had a similar problem? If so, how did you fix it?

 

I'd guess the diaphragm in your FPR is shot.

 

Where and what is the FPR?

 

It sits under the TPI plenum. It has a vacuum hose going to it and has a circle of torx head screws holding it together. Pull the vacuum hose off and see if there is fuel in it. If there is, then the diaphragm is leaking.

 

Okay so i checked the FPR, there was one rubber tube coming out of it and it was dry. I opened up the throttle and there is a good amount of gas still sitting in there. Any ideas of what i could do?... I've never had a problem like this. I dont want to take it to a shop.. id much rather do it myself. Any suggestions would be greatly appreciated!

Thanks,
Spencer

 

Try KOEO and I'll bet you see gas coming out of where the hose connects to the FPR.
