 stumbles after it gets warm
Here is the story, this is after a rebuild, we have run the car for about 200 miles with out any issues then one day I was tooling around and I go over a bump and the engine would not run above idle, fortunately I was close to home and milk it home by basically riding the clutch. There are new O2 sensors, air temp sensor, fuel filter, I did not hear any vacuum leaks. I changed out the H pipe with one that did not have any CATS. I tried to run codes last night but did not get any sweeps on the volt meter. TPS is new and right at .98 volts and seams to move evenly up as the butterfly valve opens. I am going to buy a fuel pressure tester tonight and see if that is correct, though I can’t think why the pressure would be good when the engine is cold and bad when warm. This is my first rodeo with a mustang. Any other ideas? Thanks in advance
