I am so confused..my truck has been pissing me off lately. Heres the deal, tonight I went to go pick up a lady friend of mine, when I got to her house I called her up and she said to wait outside and shed be down in a second, so i left my truck on and just chilled. First Off my truck idles at 1100 RPM? Is that unusually? How about 1400 or so when the AC or fan is on? So sometimes when I'm bored I stomp the E-brake and slowly release to clutch to lower the RPM and c how low i can get it without stalling...well this time something way weird happened AFTER I PUT THE CLUTCH BACK IN, MY TRUCK WAS IDLING AT 4000 RPM!!! 4000! I don't know if this has ever happened to somebody else in her but it was freakin scary, i thought the RPM would kept climbing and freakin blow threw the rev limited and blow the shiite to pieces. It was weird, so I put it in gear and i didn't need to give it any gas and it was accelerating at its usual rate (terrible) but it was weird. It kept accelerating through 4th gear and when I press the brake it just revved HIGHER! When I got back around to her house I shut it off and went inside. When i started it up again it was idling at 1100 as usual...What is going on here? Its not like its some old clunker, its a 2000. I'm thinking its a timing problem...opinions (besides sell it or drop a V8 please) ?
