Lean acceleration or pre-ignition type noise on intitial acceleration.
What is your question?
If it were a carbureted car, I would say it was poor acceleration enrichment. The engine operates normally at high speed cruise, although the acceleration is sluggish in reaching cruise. After a long traffic light idle, the idle collapses, the engine idles erratically and sometimes stalls. It willl start and run normally after a stall. I have replaced the out of spec coil pack, the TPS, spark plugs and faulty ignition wires. Although there is no code for it, I am thinking of replacing the CPS. Any suggestions?
