thanks the thing is it only happens when the car has been running for awhile... since im a driver on my morning runs its fine but as i get into my runs later in the afternoon then it messes up and bogs it just feels as its getting weaker and weaker as the day goes on and sometimes will feel as if its hitting the rev limiter at 4k, when i changed my plug wires it seems to be able to go longer without any issues, possible dizzy issue?
