Sc 400 Engine Sluggish

[Elya'sSC400]

Hello, this is my first time here, and I need some info on the topic. I have a '92 sc 400 the check engine light would come and go. I had it checked out, but no problem. O f course at that time there was no check light on, but the mechanic said it could be oxeygen sensors. Well Sun. nite at 11;45 I looked in my side mirror to see like fireworks that had come from the exhaust. So I pulled over and the exhaust was red hot, so I got my brother to haul me in. But I barely enough power to pull it on the trailer. so I dropped the exhuast and punched the cats out, thinking they were clogged but still no power. Someone said to put new fuel filters on it they had a car that the exhaust got hot, because of that so i am going to try that . but if y'all have any advice ,I am listening.

one of your coils is out. check them.

I don't think it has anything to do with the fuel filter...

I'm guessing there is unburned fuel getting into your exhaust and then it's cooking in there causing it to get real hot .... JZZ say's check the coils - and if they're not right then you may get what I mentioned ...

Try the ignition wire test - while idling pull each one at a time to determine if some aren't working ... this trouble shooting will get you closer to the problem ...

good luck ..

I got it fixed, a coil wire had rubbed in half by the timing belt pulley. Thanks
