1991 Toyota Tercel, 4 cylinder with 5 speed, 138,454 miles
My problem is sometimes when I first start my tercel I notice there is some sort of problem with the engine, which can happen usually about once every 2 weeks. When I press on the gas while parked I can hear & feel that the car is not running or idling correctly with the clutch in or out. I let the car run for a minute or so then place it in gear and there is no power at all and it seems like it is not getting enough gas or a bad plug or something ? When I start to drive I can have the gas floored but the car has basically no power and it is sputtering and sounds different, when I am driving and I press in the clutch the engine works fine but when I let the clutch up the problem persists. The car eventually starts to run fine after several miles and I can feel the engine start to kick in “run normal”
The car has had a tune up 1 month ago and I put a new fuel filter in and added fuel injector cleaner a couple of times with no improvement. A mechanic has looked at it with no results and this has been happening for over 1 year. Any ideas or suggestions on what may be wrong with my car will be greatly appreciated, thanks in advance.
