Surge
Hey guys,
My problem is this, Im getting a surge during driving on occasion. Mods are in the sig. Now it seems like this is only happining when it get really cold out, now i live in buffalo, ny, so the temps can get quite cold. I did not notice it all summer after i installed the tune. Now do you guys have any input on why, or what could be causing this. It seems like the rpms will surge up about 500 or so rmps for a second then go back to normal. TIA

More info would be needed about the truck and the mods done to it. I will say that when I had mine tuned at first that it would surge ever so slightly. The truck was running pig rich, we leaned it up a little bit and that got rid of the slight surge that I was having. Although in my previous truck after the cam swap, I was having a pretty good surge issue and we never did get it figured out.

Im thinking that since its only started since it got cold youve got a leak in your intake some where, try spraying ether (starting fluid) around your throtle body, intake manfold and anywhere you have clamps in your intake. If the motor revs up youve found your leak, also you might have cracked a vaccume line somwhere. Prolly need to check them too.

Thank you guys, im going to try putting the tb back to normal, and see if that will cure it. It didnt do it all summer long just when it gets cold out. Yeah it does it even when its warm Slow 4.8 I know she is getting old isnt it amazing how only a few years on a vehicle and it goes down hill.
