I am not sure how to explain this problem.
I suspect that it started after I checked the air filter few months ago. The symptoms are a bit weird: After starting the engine, without problems, the engine runs well for a while, and then it starts to run erratically and to shake like it would choke. It does that for a while when I warming it up, and then, out of the sudden runs well and this is it. If it happen to drive right away, it does the some thing and I am loosing power on gas, looks like is stopping, does the choke thing few times, and the again, starts to run well. This is happening regardless of the engine temperature, or maybe not. If I stop for two minutes, and start again, the thing does not happen, but if stays longer eg 5 minutes, it is happening again. The engine check light is not on. After choking, the engine runs perfect, no hesitation, I could drive 90-miles/h, without problems. Sometimes is not doing the thing for a few days, and then it does again. It happened once when I put Shell instead of Chevron, but when I put Shell again, did not work.
I changed sparkplugs, rotor cap, cables, air filter, most mechanics have no clue, and asked to leave the car with them for two days, not possible at this time.
Any hints please?
have the same problem?
