I recently bought my 94 YJ and Love it. I noticed it had a High pitch Squeal like a belt. But it was Vacum leaks. I replaced all the ends on the hard plastic lines going to the intake. But I created a new problem now....UGH...Now it acting like it's getting too much fuel and starts bucking and snorting while driving easy going down the road. Check engine light comes on. The question is could this be a Bad Fuel pressure regulator. Or is there supposed too be a One way Vacum connector in one of the vacum lines. Or maybe a bad PCV Valve. It had a code for throttle position sensor, could this be out of adjustment or isnt it slotted like old squarebody were...Any help will be greatly APPRECIATED....Thank You in advance...I got the codes, out. 12-33-34-55 . 12 is battery was unhooked. 33 is AC which it doesnt have. 34is throttle position sensor. And 55 is for the end of codes.
