It is a 2003 and it runs good first thing for about 10 min. and then it will bog down making it hard to even get to about 20 mph. I have repalaced a boat load of sensors and parts but nothing seems to be working. When you rev the engine and you get to about 3500 rpm the engine will pulse up and down about 500 rpm untill you let up. Help please....
Had the catalitic converter and the oxygen sensors checked and they were fine. Was told by the folks who checked them that it was the computer. Changed the computer and no difference. We have changed the coil, the crankshaft sensor the comshaft sensor the battery temp sensor the alternator the battery. what else can I do?
pulled the codes from the computer and there were none, and my mechanic is working for free.
