hey guys
i have an 87 4 runna with a 22re motor, it was sputtering and hesitating. I thought it was the exhaust leak. I put in in new donut gaskets. I then threw plugs, wires, cap, rotor, fuel filter at it to make sure those weren't an issue either. i took it for a ride and didn't seem any better. when i got it back to the shop i saw the CAT was glowing red! I then figured it was the cat, so i replaced it.
It is NO Better at all and the new cat is glowing too!
What should i look at next??The muffler is recent too.
I feel like it is dragging a boat anchor and sputtering still!!
Please help, any one ever run into this???
