Cranks fine missing some pops like it timing is off about 60mph is all it will go

If it seems like the timing is off -- then maybe the timing is off! This vehicle does have a timing belt. It is possible that it has jumped time. Has there been one replaced recently? Further, if timing is good, you could also have an exhaust flow restriction. Either way, with OBD II available for diagnostic testing, a good diagnostic tool and shop manual for reference should lead the way towards a successful diagnosis.
