My 1995 Cadillac Deville with 4.9 liter engine hesitates when I accelerate. How frequent? It seems that depends on what the outside temperature is. I bought this car in 2000, and have had this problem since 2001. My mechanic feels it's a computer problem. He says my car has 3 "computers". He's not sure which one to replace, so he would replace one at a time until problem is remedied. He suggested I just drive it as it is, so that's what I've done. Anyhow, if I remember right, the computer trouble code is P041 (which has to do with the camshaft position circuit). I replaced the camshaft position sensor, and that didn't help at all. I troubleshot this circuit the best I could, and didn't find anything. This hesitation problem is annoying. I would like to get it fixed without having to replace all computers. Any suggestions? Thanks in advance.
