My car sounds like it have aftermarket cams

[thector1]

Hey all! like I said in the tittle, my car sound like it have aftermarket cams. Just installed a vrsf intercooler kit and a 1g tb cause mine was leaking. I have a 95 gst stock internals.
After I got rid of all the leaks it started sounding like that.. How do I know if I got aftermarket cams. I looked at them and the only mark I saw was a D
Thanks!

Sometimes a bad misfire will make a car sound like it has cams. Check your spark plugs and wires to make sure they are ok.

Gonna change the plugs.. Cause when I checked them they looked white. The cables are new..

Also the misfire is only at idle. Everything else is fine

Ya I say check spark plugs an timing. Could b a weak coil pack

An do a spark knock test too so you can see if ## coil an wires r putting out great amounts of spark to spark plugs

Another issue that might be causing your car to sound like if you got cams is if one of your injectors is not firing up and is stuck shut. Do you have a CEL?

Check the timing too

Got a new o2 for the front, got rid of that code and now got a diff one, p0425. Got full exhaust so the back o2 is acting up. Will check all the stuff you guys said this weekend. Anymore ideas welcome, Thanks!
