Hey guys...A wierd problem has just started a few days ago. Under boost my car hesitates. Like its holding back...Fuel filter maybe? Any ideas?

if you don't have anything that retards the timing under boost, then it's very possible it's something in you're fuel system(ie, injectors, filter, etc)

My old Probe GT did that and it was because my sparkplugs went bad. I put in a new set and couldn't believe the difference.

My friend had the exact same problem with his Talon. It was a misfire in one of the cylinders. Could be the spark plugs or the wires

Hope that helps

Well I went to corksport and they hooked up a fuel pressure gauge..The pressure regulator was stuck shut and then they tested the fuel pump..only putting out 30lbs!! My new fuel pump came in and I pulled the old one out and to my suprise the hose that connected the top of the pump to the assembly blew off! We checked the pump and its still bad so im gonna replace it and we also took the OEM fpr out since I have a RRFPR anyways....Ill keep you all posted.
