my car stalling when warm and damp.

[bbg518a]

I have a’91 Toyota Camry 4 cylinder, automatic transmission with AC that has about 175k miles on it. The car runs well except for an intermittent stalling problem. The car will start and run normally until the temperature gauge starts to rise, at which time it will quit when the accelerator is pushed down. If I let go of the accelerator before the engine dies, the car will idle. If I nurse it through the "bad spot", the engine will pick up and run normal. Once the engine is warmed up past this point, the problem disappears. I have replaced the spark plugs, distributor cap, rotor and wires, checked the fuel pressure (it is normal even when the problem is occurring), replaced the fuel filter There are no fault codes in the computer. This problem seems to be worse when it is damp outside, but I can't find any particular electrical problem. Is there any specific system that I should be checking that would cause this problem ?.....bbg

i inquired a mechanic,he suggested coolant sensor, where is it?and is it hard to replace? thanks in advance!

Try to replace the little condensor in the distributor (get oem part). That should fix the problem.

Good Luck

Is your thermostat OK?

The Condensor (capacitor) will come & go with heat... It is connected on the coil terminal & will short out or leak... When it leaks it will drop the voltage to the coil... I have a 92 Camry, the condensor shorted, took out the 30 amp. ign. fuse.... Toyota seels this part for around $4.50 (may have to order it)....

I, too, have a similar problem (as bbg518a) with my '93 Camry LE - auto/4cyl/ac/142,000.
The car starts up fine. About 1 1/2 miles away, I'll come to a stop sign or stop light and it'll stall. It will start right back up, but I have to gas it in neutral and then we're off again without any problems whatsoever the rest of the trip. I had noticed the problem last winter on damp days. Now the problem happens everytime.
I asked a mechanic about it and he said "old car". Any more insight as to where to proceed (or if bbg518a figured it out)? Thanks.
