I was having a problem with the car pulling or tugging at low RPM's and low throttle. I had a TPS code but that went away with a new TPS. The car isnt tuned totally yet and is still rich. It almost feels like a miss so Im going to change the plugs...but only happens when mentioned above?

Is this cam surge? fouled plugs? too much fuel?

Its not so much a problem as much as it is annoying....

 

Could anyone take a guess?

 

I already gave my opinion in my other thread and still think that it is cam surge. It will only go away with a really good tune. I have PCM4Less and still have cam surge. Under 2k and no throttle you will probably have jerks/tugs and gets progressively worse until you add throttle, am i correct?

 

Your right on...I was hoping for a quick fix. Thanks

 

I was told that cam surge is technically called, "The Hot Rod Massage"

Hey Matt...Sounds like cam surge to me. I'm getting a bit of it below 1500 in 1-3.

If I try to idle through a parking lot it gets SERIOUSLY "jumpy."

So how do you tune this out? Anyone know?

Ryan mine is only when barely on the gas in 1-3, at idle its there but not as noticable.

 

Matt...I bet the extra cubes and increased compression helps yours out a little. I was under the assumption that by manipulating the timing you couldget rid of it. However, I know NOTHING about tuning .

Let me know if you find a fix, although its not that bad for me - I don't expect it to drive like stock .

Ryan true, they cant drive as nice as they used too.

Hopefully timing will be able to take care of it...
