About 5 weeks ago my 2008 Hyundai accent’s check engine light came on. It came on right after I filled up a tank of gas and started running a bit rough. About a year ago the same thing happened, and it turned out to have been because of some bad gas (I ran the tank down, refilled and everything went back to normal). I assumed that was the same thing this time because the gas was from the same location and the problems started right after the fill-up.
I drove it for about a week and then it stalled out completely. Rpm wouldn’t go over about 2,000 and if I tried to drive I wouldn’t go over about 10mph. I took it into the local shop. Replaced all kinds of fuel sensors, spark plug coils, and the main computer, and I think the fuel pump (all of which got fried). The error codes are all fixed and the car idles just fine. Only problem, when you put it in gear to drive it almost immediately bogs down, rpm stays below 2k (still) and eventually it will totally stall out.
The shop is now saying they think it’s the catalytic converter - but they aren’t sure. They have had my car for over 3 weeks now and I’m losing (have lost) faith. Plus it’s already cost me $1500 and I’m not wanting to spend more on their hunch that it’s the catalytic converter.
The car idles smoothly now, no error codes. But as soon as you try to drive it barely moves. It feels like there’s a governor on the engine or like there’s not enough fuel getting through.
Thanks for any advise on what to try next.
