Question about 1989 Toyota Corolla 2 Door

1 Answer

Engine misses badly at freeway speed and problem gets worse uphill. The tachometer gyrates wildly. Finally lost power and stopped. Waited a few minutes and restarted, but barely made it home. Engine starts at home, but when increase the engine speed at idle, the tachometer still gyrates at the higher rpm.

1999 v6 firebird misfires on #6 cyl when under load, plug was fuel fouled last time I had it replaced, but keeps missing only when under load. no other problems.


if you've changed the spark plug and no difference, then it's time to swap the coil with another cyl. coil and see if the miss goes to the other cylinder, if it does'nt follow to other cylinder, then I would replace that injector !

Stop running while doing 65mpr on freeway, first started dieing with fast left turn, got worse started dieing when i hit a bup in road, then started dieing with right or lift fast turns and bups in road,...


Check the Timing belt and the fuses. If you have installed anything that has wires that you connected into the fuse block check those to make sure one hasn't come free and shorted a fuse on the fuse block or Power distribution box in the engine compartment. Also, and I know this is a long shot, check the oil level in the engine to make sure your bump is working and that the sensor is responding correctly. I had a sensor go out once and when the engine got low on oil it didn't register but when I made turns you could hear it and feel it with a lose of power.

Weak humm when driving over 35kmh.


possibly a wheel bearing or tyre noise from badly worn tyres
while driving in a straight line and noise is present change lanes or shimmy car left and right if noise gets worse or better wheel bearing problem
also if noise gets worse in normal town driving speed and gets less at higher freeway speeds check your wheel bearings

Engine knock when going uphill +...


Oil pressure might actually be a bit high for idle. High or low oil pressure in an older engine tends to be indicative of some serious issues. Oil pressure that is too high tends to be a clue that you have serious carbon build up. That aside, have you tried running a higher octane fuel, or perhaps adding an octane booster to your normal grade? Pinging can become knocking in a badly worn engine. One recommendation: At your next oil change try substituting a quart of marvel mystery oil or lucas engine oil treatment in place of one quart of your normal oil. Both have some pretty good track records for helping to free up sticking valves and break up carbon in older engines. I'm an old timer myself, and I personally swear by Marvel for older engines. There is no "rebuild in a can" but Marvel comes close. Give those a shot, let me know what happens.
