misfire / hesitating... could be fouled o2 sensor? i had the TR 230/236 .590/.598 112 LSA cam put in recently with a full dyno tune. sometimes under load the car will bogg down in the upper RPMs..around 3,000-3,500 range. i did have the codes read and one did have something to do with the front passenger o2 being fouled. do these symtoms match up with those caused by a fouled sensor? i did buy a new one and am waiting on an extention so it will fit. im guessing that when i put the new one in the car will run better?

Is this under WOT or normal shifting? If it runs OK below 3K 02 sensors would not be my first guess. It would be nice to get some readings from the computer while you are driving. TPS could had a bad spot. Let us know what fixed it.
