1986 Toyota Celica Repair Question
Toyota Celica Rpm Problem
It's a stick, has 86k miles ( yes that's accurate )
the car sat for several years in a garage and a teenager had it before me for about a year,
so there are some silly things done to it but all in all a great buy when i found it this year feb.
The car had power, very quick and peppy. A joy to drive.
2 months ago the car lost it's power / acceleration.
Not to mention the MPG has significantly decreased.
Plugs, catalytic converter and fuel filter.
Wires were replaced last year in December. ( they looked new when I bought it)
Also the K&N air filter i took off and cleaned thoroughly and properly.
Best way i can describe the problem. it's as if I can only give the car 1/4 throttle. Floored, or barely pushing the pedal, same rev speed.
super slow to rev up to 3.5k rpms... then it gains some power back.
literally no power while driving in ANY gear unless it's over 4k rpms.
If i'm driving in 5th on the highway, any incline causes the car to loose speed. ( even at 80 mph )
when i got this car, it would hit 100 on the hwy quickly, no issues
A, compression is gone in one or more cylinders. ( new rings? )
B, Fuel pump weak ( altho i figure this would affect power at higher rpms??)
C, a sensor.
I'm not a mechanic, but pretty handy with tools and I can read a manual well.
Any thoughts or input would be greatly appreciated as I NEED THIS CAR DAILY.
what about the timing belt???
check the compression. check the fuel pressure. get back to us with those numbers.
i believe it has a mass air flow sensor but make sure there is no cracks or breaks in the inlet hose to the throttle body.
good, glad to hear you got rid of the k and n. they contaminate the sensors with oil. they have little or no effect on performance.

I just had the converter put on YESTERDAY due to advice from a mechanic friend...
the car idles much better, and the acceleration is SMOOTHER, but not any quicker.
the timing belt isn't worn, however it does have more slack than i believe it should and it makes a rattle when RPMS are under 2k ( tensioner issue? )
luckily my drive to work is only 3 miles....
paying a shop too check compression and timing and fuel pressure is out of my budget right now...
when i get the tests done, i'll update. thanks for the help
PS. nice name Roy
