Check engine electronics light always on because of unrelated evaporation censor issue.
Having issues with my car, and my mechanic is a little stumped. Anyone here have advice?
Maybe in the last week or two, noticed the faintest flutter of the engine when stopped at red lights. Was faint, seemed like no big deal.
This last Friday, had been driving 45mph for 3-5 minutes (cool day). Stopped at red light, engine freaks. Got intermittent revving and lurching of whole car. “Acc.skid control” warning light comes off. I pull over in a fast food parking lot, turn car off, calm down cuz I was freaked out by aggressive lurching. Pulled over maybe 20 minutes. I decide to drive to my mechanic who happened to be nearby. Turn car on, and it stalls four times, in the time it took me to back out of the parking space I was in and get to the driveway.
Where things get interesting:
Mechanic replaced “failing mass air intake sensor”. Car seems 95% fixed…
I go to pick t up today, and the same issue seems to be happening, but way less dramatic. Did a ride-along to show mechanic the issue (because they couldn’t replicate it), and he said:
Seems like the engine doesn’t know what level to idle at, and hesitates to shift gears. Issues appear more when driving slow. This has only been an issue since Friday. Never noticed ANY other signs of transmission issues. He says he’s not sure what to do, and will try checking the transmission fluid and clean the throttle body.
I’m hoping for a confirmation or additional suggestions to get this fixed! Anyone have any suggestions? I REALLY am broke and just got this car six months ago!
