1993 Chevy Lumina
Ok this was the craziest thing I have ever seen. Got the o-rings for the fuel pressure regulator got everything put back together, no leaks. Finally got it to start was running very ruff and backfiring but figured that would happen since replaced alot of part and sensors and clean up alot of gunk. It was parked in the driveway and hubby was going to back it up abit and quit for the night. He touched the gas a little bit to back up and it shot back like a rocket and hit out house ( house is fine ). It seems not to brake all the way to the floor. He put it in Drive and it shot out of the driveway like a rocket he was like a rudder on a boat an could not control anything except the steering, Missing all the cars parked on the street. Finally got it stopped and nursed it back to the driveway and when got in the driveway put it in park and it died. Any ideas? 1993 Chevy Lumina Base 3.1 engine V6. Replaced the Fuel Pressure Regulator, Throttle Position Sensor and Idle Control Valve and Spark Plugs and air filter. I am afraid for him to try to drive it again.

Re: 1993 Chevy Lumina
Sounds like you need more help than we can give you from here, so the engine raced in gear out of control without stepping on the gas? Why were these parts replaced to begin with?

Re: 1993 Chevy Lumina
Knock the big vacuum hose for the brake booster off or something?
Would explain a lot of what's happening...

Re: 1993 Chevy Lumina
Think found out the problem the gasket between the plenum and manifold slipped out of the back. So looks like air is getting in there and yes very cold air was down in the 30 Sat night. Gonna take everything apart again and she what can do. Thanks for your help

Re: 1993 Chevy Lumina
Sounded like a massive vacuum leak.
And that would be massive, yes
