Hey guys, really hope you can help me out here!
I have an '01 GT with 158k on the clock. Today while I was driving to work I suddenly had a huge loss of power, the engine wouldn't rev past 4000rpm, and I couldn't get past about 55mph. The engine was also hesitating very badly. If I put the pedal to the floor the motor makes a horrible knocking or detonation noise tryin to rev it quickly or above 4000rpm. Had a friend stick his hand behind the exhaust while I revved it and he said there wasn't much flow and the exhaust was really hot.
There strangely is no CEL....
Things I reckon may be wrong: clogged cat, clogged fuel filter, bad fuel pressure regulator, dieing ffuel pump, or bad MAF.
Anyone else have these symptoms and what the fix ended up being?
Thanks in advance for your help!!!!
