hey guys im having trouble geting rid of a stumble after it worms up does it before 3500 rpm then its fine. i just got it inspected a wek ago and i drove it for 2 days with no problem even raced a lincon navigator but i started it up the next morning to go to work and it ran fine till i got half way there then it was like the timing got mesed up so while it was running i took the distribitor and spun it a little clock wise and it ran better and reved better so i went to work ......then left work in the after noon and it only got half way again but this time it wouldnt even go down the road it was like a rodeo but got it home took a timing light to it and got it where it needed to go so to shorten this if i jently push the gas to the floor like real slow it will rev high but if i try to rev it fast or put strain on it it dies its got a new wts, maf, no egr,plugs, fuelpump and filter, injecters, ats. but the car runs fine when cold PLEASE HELP!!!!!

I'm having trouble deciphering your post.... but I would check for codes. Maybe your O2 sensor ?

sry i replace the o2 sensor and the ecu aint reading eny codes ill try to explain a better way then before when the car is warmed up it runs like **** misses at idle and when u give it alot of gas it stumbles and if the rpm rises it stumbles all the way up i have to jently hit the gas to rev but when cold every thing is fine
