Help???
I posted this on the NO performance engine only forum and no one would respond do you guys have any ideas. OK my 05 is really acting up if you rev er up in park or neutral say to 2200 rpm the motor just hangs there banging out I can take my foot off the throttle and it will just sit on 2200-2000 rpm for ever until i pull it ino gear or turn the truck off????? It sounds like a JAP ROD running on the rev limiter popping and missing. The reason I noticed this is the truck has started idleing really rough and I tried patting the throttle to clear it up like an old gasser. The real issue is that the truck has started pinging really bad while exelerating. It sounds like an old gasser that the timming is way too far advanced.... Any ideas I went threw the rokers already and the lash was pretty good. I found a thread about the A/C wires rubbing and causing the motor to run bad. but my wires looked good.It really sounds like detonation.ANY IDEAS PLEASE?????

sounds like you could have a bad TPI. If it's bad or going bad, it will send the wrong signals to the ECM which in turn could be what's advancing the timing. With a wrong signal from the TPI, the MAP and fuel pressure sensor will also be receiving the wrong signals
It would help if you filled out your sig to see what your truck has installed. One way to find out if these are your problems is to get connected to a starscan.
