Update. Had a shop clean the throttle body and injectors. Drove again for aboyt 40 miles. And it did it again. Only this time it stalled. Never did that before. So far I,ve had the car in 4 shops, Have spent about 400 dollars. And still the proplem remians. I guess I,ll have to figure it out myseft. Need to learn about sensors and fuel injectors and the like. I,m an old chevy short block man. Can work on them okay. But anything after 1990 I,m lost. I guess I,ll go ahead and replace the catalytic converter and oxygen sensor. And then every week replace the other sensors. If that don,t work, I.ll replace the injectors. Rebuild the throttle body. I would have thought a dealer and some of these shops could have at least told me what the issue could be. With all the money I,ve paid to other people. I,ve could have done all these things already. I,ll never take a car to a shop again. If I can,t fix it myseft. I,ll junk it.
