gen3 Camry enginer stutters.....?

[The Wolf]

I've got a problem with my 1994 Camry's i4 engine. When I'm slowing down, the engine will sometimes stutter and die; this is a random problem that doesn't occur often. It's only died twice. Suspecting the fuel system, my dad and I changed the fuel filter. Didn't help. This seems more likely to occur when I drive the car hard; say, reving above 4000 rpms for a few minutes from stops. I've called several local garages and was told that it couldn't be the injectors (as I first suspected), because the problem would occur all the time. After asking my brother, he said someone at his job had a similar problem on a 1993 and said it was the MAP sensor. I have also remove, checked, cleaned, and reinstalled all 4 spark plugs, as well as tested the plug wires. All is OK there. Any suggestions would be much appreciated... I believe that it could be the MAP sensor or possibly distrubtor, which I haven't checked.

i dont know about map sensor, but maf for my gen 3 was only 50 $ cad at the junk yard, so its not expensive to try out

what about the idle adjust thing? maybe clean that off

Try cleaning your TB(Throttle Body) especially the butterfly mechanism, maybe its sticking and not giving the right air/fuel mix ratio.

Alright, I finally took my Cam to the local Toyota dealer. I paid $74 for diagnostics, in which they found that I had a weak ignition coil. So I decided to let them fix it, as they already had my car and I was out of town. It was another $182 for the coil & labor. Final cost: $286, with a $10 environmental fee. Anyway, my car has stuttered twice since then, but each time I was able to rev up the engine and it stopped. That was about 2 weeks ago, so I still don't know what the problem is......

bring it back to the same place, tell them they missed something in their last diagnostic

fuel pump? does it do it at wide open throttle or just idle?

try ignition most likely the igniter coil inside of the distributor cap
