Can anyone tell me how many miles you have to drive after your codes have been cleared, and problems fixed, before you can run through emmissions. I just cleared and repaired air intake check valve(passengers side),and cleared code but emmissions station says I have to drive or wait or whatever, till whenever? I still have to retest, but when?

I have a 2006 Silverado LS 1500 WD ext cab, a 6 cylinder with 4 speed auto transmission. Everything works fine except when I'm using cruise and doing about 55 and I reach a small hill, the tach jumps to twice the RPMs as the transmission shifts, then the RPMs abruptly drop to normal again. The tach is always in the safe zone. The dealer said (without driving the truck) that this was normal, but it's kinda annoying. Is there a problem?

Hi everyone, Recently, my 2k Silverado 4.8L has been dificult to start when it's hot. I suspected my EGR valve so I disconnected it to see but got the service engine light on now. I know it's not the EGR now but the light stays on. I remember my dealer telling me once how to reset this but I forgot. Could anyone help? Thanks

Replying to: gangof4 (Sep 16, 2006 11:00 pm) Your RPMs do increase when the transmission downshifts but not as much as the tach would indicate. Any sensitive electronic meter will do that given a sudden change in input. It's called overshoot. I don't think you have anything to worry about. |
