I have a '90 Cadillac DeVille, pulling away from a stoplight last night the engine started revving %26amp; would not slow down even with brakes, as if brakes not working. Approaching next light, had to throw into park to avoid hitting car! (Not good!) Still racing, shut off %26amp; restarted, still racing. Repeated 5x, then normal. Going into next gear, start revving again, slowed down, it was fine. Transmission? Only had car 3 mos, don't know when last tranny work/check done. Told at last oil change DON'T add tranny fluid until tranny checked out - could do damage. True? Don't want to hit someone because my car won't stop %26amp; don't want to tear up tranny by throwing into park again. How much for tranny work? Very limited funds. What to do? Please help!%26039;90 Cadillac DeVille tranny problem? Safe to add fluid if needed?
No, that is a throttle issue if the engine was racing. Check the linkage, if it is good, a good bet is you need an Idle Air Control motor. It sounds like it may be sticking. I would not drive it until you fix it if possible, because you could get in a very bad accident, espicially if it is racing!%26039;90 Cadillac DeVille tranny problem? Safe to add fluid if needed?
Sounds like a stuck throttle body. There's a spray cleaner for it, and / or gas addittives for it. Stop by the auto parts store and ask the counter guy.%26039;90 Cadillac DeVille tranny problem? Safe to add fluid if needed?
your having a throttle body problem,,or the linkage is sticking on it,,this one has a cable that operates the throttle body,,you need to clean it off ,and put some penetrating oil on it so it will work easier ,,i own a repair shop,,and have seen a few cars that stick,it can be dangerous to drive like that,you need to fix it,,or have it fixed,,good luck i hope this help,s.
