Question about 1991 Toyota Celica

1 Answer

L have a 1991 Celica altrac. It starts and runs fine, tickover no problem. After about 20 miles driving it suddenly has no response to opening the throttle. It doesn't cut out and picks up really slowly on really tiny throttle openings. When it does this I stop, turn off the car, wait 20 seconds and re start it. It's instantly back to full power for about another 20 miles. I've changed the throttle position sensor and it made no difference. Any ideas?

You may want to check for moisture in your plugs or coil

Car shuts of suddenly while driving. Starts back up after 20 minutes.


When the gas-cap is plugged, you build up vacuum in the gas- tank and cause the gas flow to stop.
Use premium gas only, ETHANOL in the mix is attracting moisture/water which is part of the problems.

Automatic or manual...?
If automatic>>> Check transmission fluid. If it's full>>> Need new transmission.

I have a 91 toyota celica that will not go when put into gear.


Have you had problems with clutch slipping up to this point? Like engine revving up and no change in speed while driving. Like going into 4th or 5th gear, letting clutch out, giving gas, and feels like no response? Engine just revs up? That's a slipping clutch.
If that's your problem, you need a new clutch.

My 1991 Toyota Corolla drives fine and then suddenly it starts to hesitate.


mine did the same thing and it was oxygen sensor
since engine light came on there should be an error code
on computer.Get a diagnostic checker or take to a garage and have them hook uo to the diag connector. I bought a diagnostic checker few years ago and it has come in very handy
sure hope this helps!!
