Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
good evening my name is ***** ***** I will assist
it sounds like the cat converters are clogged shut.
have him remove the upstream o2 sensors and see if it runs any better. that would be a starting point
Thank you. I told my husband and he said "He could be right". He will check it out tomorrow. Wouldn't that throw a code?
that is not fuel control. it is mechanical. there are no codes for mechanical controls
please dont forget to rate me as it is the only way I get paid for my efforts
how are you making out
Sorry it took so long.
ok, he removed the exhaust system from exhaust manifold to the tail pipe and took it to a muffler shop. They checked it out and it passed with flying colors.
Removed alternator and had it tested - it was bad, replacing it. Also, the alternator wires looked like they were too close to the exhaust sys. as they looked a little crispy - fixing that too.
Going to put it back together tomorrow. Since we have already done everything else, his mechanic buddies ( a couple of them are master mechanics) have suggested:
Body Control Module
Transmission (Since it's worse in gear)
So, if we still have the same problem after getting it back together, where do we go next?
Help please. Thank you.
taking the exhaust to a shop checks nothing. you needed to do a back pressure test to test the converter, not a exhaust shop. I never told him to remove the exhaust at all. I said to remove the sensor and test drive. you may have the same issue until the proper testing is done to confirm the failure.
