I have a 93 camry that hesitates and sputters when accelerating. It seems to do it worse after it's warmed up. It idles and revs up while stopped just fine. Only does it when accelerating. Doesn't matter if it is slow or fast acceleration. I recently replaced the fuel filter with no improvement. Also added HEET in case I got bad fuel with no improvement. Any ideas what I should do next?

They are bosch wires. No date but probably not the originals. Today it is running fine but missing when idling, so just the opposite of what its been doing

If its only missing at idle then i would look for vacuum leaks hoses etc.

Every engine is different and has there problem areas you would have to check all the vacuum hoses intake manifold etc everywhere there is vacuum running.Injecting smoke into the vacuum system is the best way then look for escaping smoke.But without building a smoke machine.To buy a smoke machine is really expensive i built my smoke machine it works great.You can try spraying carb spray around at idle looking for a increase/decrease in rpms stumbling or dieing.But smoke is by far the best way to look for vacuum leaks.
