I've posted about this before, but then I went and did a few things I thought would help, but so far.... well still idles like crap. Car feels like it's stumbling during acceleration, idles rough, and feels like it's missing some power.

Done in last 2 wks....

New spark plugs ( NGK coppers )
Cleaned EGR valve
Cleaned throttle body out
Seafoamed
92oct Gas

STILL WAITING FOR COILS to replace cracked ones ( you know who you are )

So any ideas??

 

If you bought the coils from me you would have had them 2 days after paying.

 

Ya ya I get the point. There was an addressing issue, it's on the way.

So, Jeff any ideas???

 

Idle Air Control Valve, check the timing, check grounds, check for vacuum leaks, etc.
