rpm's dropping really low Posted By: 00MaroVsix On: 05-16-2008 @ 20:34:20 Reply | Edit hey guys new to the site but definently not new to motors nor new to f bodies. this is my second 4th generattion camaro and my buddy has a firebird that i work on quite a bit. sometimes while driving my rpm's drop really low just for a second and the battery gauge drops down to like 81/2 or 9 volts and then kicks right back up but only at idle or at low low speeds mostly when turning the wheel or putting it into reverse from drive. and my headlights and dash lights dim. any ideas? thank you Posted By: Jeremiah On: 04-18-2008 @ 19:38:34 Reply | Top | Edit Do you have an aftermarket stereo?

Ever have trouble starting it? --

Time for an oil change and transmission filter and fluid too. Fuck high mileage. --  [ Edited on 04/20/2008 @ 22:46:34 ] Posted By: 00MaroVsix On: 04-28-2008 @ 00:15:40 Reply | Top | Edit this is what my car is doing when i turn the wheel http://youtube.com/watch?v=ONMMsLsR7p4 Posted By: Jeremiah On: 04-29-2008 @ 09:35:50 Reply | Top | Edit Yeah I'd get that checked out before you wind up stranded because of a dead battery or alternator. There is a chance it could be a bad ground somewhere too. -- 2005 GMC 1500HD 6.0L, 2006 Pontiac Grand Prix 1991 Camaro - 24 Hours of LeMons race car. Pics: ftp://72.167.14.32/24hoursoflemons

The most telling thing seems to be amperage output. Usually people come in and say they loose some power with lights or what not. I check the alternator with the motor at 2000rpm and all electronics in the vehicle on, and voltage can be decent while amperage might only be 15% of what it should be. -- 1982 Z28, 383, D-1SC intercooled @ 10psi, trick flow heads, solid roller cam, 3.73's, stall 9.97@137, 1.48 60', 633rwhp@7400, 472rwtq@6800 AIM:CHATV400
