Two mechanics and no luck?

First of all it is a 1995 camry with 79000 miles on it. It has always run fine until one day it just started to feel like the engine was missing around 45-50 mph and when you idle or reverse. So, we took it to a mechanic who said it was tune up work. The spark plugs, spark plug wires, rotor, distributor cap, fuel filter, air filter were all changed. We also ran fuel injector cleaner through the gas and replaced a broken tortion control mount. The problem persisted so we ended up having to take it to another mechanic who said I had a broken engine mount. So, he replaced that and balanced my tires. The problem still persisted, although it wasn't as bad it's still frustrating to spend this much money and have the same problem. So the question is what could be wrong with it and how can it be fixed? If so, how much would it cost? Thanks!Two mechanics and no luck?
look at the MAF there is a small wire that gets gunk build up and clean that little wire and viola!

look at the air tube and its usually 2 phillips screws near the air filter and a plug in of course. remove the screws and carefully pull the MAF and clean with light spray of electrical parts cleaner of MAF cleaner they have it at walmart in the auto section. DO NOT TOUCH THE WIRE! its very fine and easily damagedTwo mechanics and no luck?
it's probably nothing to do with the ignition system, try looking to see if you have any malfunctioning sensors, especially in the transmission, a broken speed sensor will cause the engine to buck or misfire at certian speeds. Since your car is OBD I equipped it may be harder to find some one to scan it.Two mechanics and no luck?
Ignition coil could have a short in the secondary. When you need extra spark the energy isn't there.







Toyota uses speed / density to calculate air flow. You don't have a MAF.Two mechanics and no luck?
Careful not to lock yourself in your car too. That would be a double wammie.Two mechanics and no luck?
could be an air idle sensor,those mechanics ripped you off you didnt need a tune up.rotor??? you mean rotor as brakes? omg......good luck anyway.Two mechanics and no luck?
I'm going to break a rule I've lived by all my life and recommend you take it to the dealer. They're probably better equipped to find the problem.
