Any ideas? My car revs up high fpm no check engine light.
Okay, I have a 1992 Cadillac Seville sts. Has a 4.9ltr pfi
So far the list of things I've done,
1. A transmission service dropped the pan new fluids filter
2. Octane booster in my gas.
3. New plugs.
4. New fuel filter
5. New catalytic
Any ideas what could be causing me to over rev when I
step on the gas pedal feels like the car could be in limp
mode but there is no check engine light, but I can get up to
100 if I go down hill and it decides to shift past 3rd. If I hit a
hill forget it lol my car slows down over revs won't lose
speed unless I floor it and then it drops slowly and wo t
gain anything. No idea what this could be I have done the
lucas no slip when I did the service and it shifts fine if I
don't floor it no hard shifts notging.
Sounds like the transmission is slipping. On a '92 (OBD I) GM you won't necessarily get a check engine light for a transmission problem. HTH. -Jim
It's mostly when I hit a hill.
The car shifts fine, but lack of power on take off and no power on hills, any idea I'm thinking timeing or a vacuum leak
Lack of power and late transmission shifting could be a worn timing chain. Is it running hot as well? HTH. -Jim
