Please help! Cars acting really weird - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

So first off I have LT's, straight piped, no cats, tuned by Ted J. I have CEL codes P0030
P0050
P0053
P0059
P0135
P0134
P0155
P0300
P0443 ,Anyways here's the problem with my car. If I let my car idle for a while it'll start to sound like it's turning into a cam, it'll get slower and slower then cut off. It'll emit a bad smell as well. When I'm driving and that happens it won't let me increase speed, it's like stuck going over 2k rpm, I've noticed knocking like sounds when I did try to increase. When I pull over I turn the car off turn it back on and it's good to go. It even sounds weird when I downshift, it's like it wants to rev and it will but then it'll stop.

Talked to a couple of mechanics in town and they were telling me it could be that I'm running straight pipe and that my engine isn't getting enough pressure that it would get from hi flows, x-pipe, and a non muffler delete.
I contacted Ted and he told me to log my car using the SCT thing off their website. I plan on it tomorrow but has anyone had this problem? Please help. Any inputs would be nkce

That right there is some B.S.

Listen to your tuner. Do what he asks. Something is obviously wrong with the tune.

That's exactly what I thought as well

The tune may not be the culprit, however that little line about no enough back pressure is BS.

The misfire and Evap codes could be causing the heater codes also. Do what Ted suggested and get him some data logs. Does it knock all the time, even at idle?

Masongabriel · 08-20-2015, 01:33 AM

It only knocks when the car doesn't wanna accelerate over the 2k mark @1killerss

1KillerSS · 08-20-2015, 11:34 AM

What do your data logs show?

Had VERY similar problem but with no tune. Turns out the O2 extensions touched the header and melted down one of the wires. It caused a short and popped the O2 fuse. Replaced the fuse, tied down the extensions and we're good to go.

Will tune soon.
