We tried fuel injector cleaners, but they only work temporarily and changed spark plugs and that only helped a little. The engine light goes on and off at will and autozone could not read any codes. Any ideas?
I have a 1999 corolla that will not accelerate over 20 miles per hour could it be the fuel injector?
check if your exhaust is clogged. take your car to a repair shop, you may spend more money while you replacing parts.
possible mass air flow sensor

sounds like cat converter is plugged up see under car when running if it is glowing or smells like rotton eggs if not or feel exhaust pressure is weak
could be the tranny
take off from the cat- back of exhaust if your speed improved 1 or 2 things you can do 1 replace the cat which wold run about $400 or 2 which might not pass emission test is to gut out the cat , find an exhaust pipe that fits in cat housing and get it welded then put exhaust back together
