I have a 1998 honda civic LX that slips very very seldom upon acceleration. It happens under light acceleration and medium acceleration (I dont accelerate hard enough to see it slip at high acceleration, it might!)
What happens is, the car stops accelerating and simply idles. As the motor idles the car drifts and slows down. I have never done it, but I bet in this state I could come to a complete stop just by drifting if I keep my foot in the same spot on the accelerator. When I change my foot, and accelerate harder, the car wakes back up and keeps accelerating like nothing even happened.
I dont think it is the transmission slipping, because in that instance revs would climb and acceleration would halt and that is not the case. I recently gave the car a huge tune up, here’s the list
Valve adjustment
Oil and filter change
Cleaned throttle body and IAC
New distributor and cap (Plug wires aren’t really in good shape)
New spark plugs
New air filter
Set the timing
New belts
Cleaned injectors
Cleaned battery terminals
I dont know what could cause this problem! The only thing I have come up is the Possibility a TPS (Throttle position sensor) going bad.
The only thing that I know of that is wrong with the car is the exhaust manifold has a big crack in it right before the upstream 02 sensor. No doubt this leak is messing with the cars readings of the AFRs. Could this be part of the problem? It is throwing a code for the catalyst system.
Thanks!
