BillSSS03 Posted February 20, 2010 Report Share Posted February 20, 2010 i have a 03 ss w/ the radix on it,the throttle body upgrade,it all of a sudden started runnin rough at idle in park and in gear and the check engine light came on,then a week later it started runnin good and the light went out ,then two weeks later it started doin the same thing,my predator tuner says it is runnin lean in banks one and two,has any one else experienced this ,at times its like the engine surges then it idles down so low it almost stalls ,what could cause this to happen,thanks for any help in advance Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted February 20, 2010 Report Share Posted February 20, 2010 Those are the only two codes you threw, a P0171 and a 174? No P0300 or P0101? What TB did you upgrade to? Quote Link to comment Share on other sites More sharing options...

chpspecial Posted February 20, 2010 Report Share Posted February 20, 2010 Possible vacuum leak, a bad MAF, bad 02 sensors, Plugged injectors, failing fuel pump, failing fuel pressure regulator, and even a bad tune Quote Link to comment Share on other sites More sharing options...

Vaquero Posted February 20, 2010 Report Share Posted February 20, 2010 maybe clogged fuel filter? Quote Link to comment Share on other sites More sharing options...
BillSSS03 Posted February 20, 2010 Author Report Share Posted February 20, 2010 maybe clogged fuel filter? i am gonna try changin that toimorrow along wit cleanin the maf ,thanks hope thats it,im also wondering if it could be an internal vacuum leak ,in the manifold gaskets Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted February 21, 2010 Report Share Posted February 21, 2010 Could be an intake gasket, but if the Radix has been on there a while, I highly doubt that is the problem. Did you retune the truck for the 90mm TB? Quote Link to comment Share on other sites More sharing options...
lilmarv1117 Posted February 21, 2010 Report Share Posted February 21, 2010 did you do the throttle body and j-tube upgrade recently?? it sounds like something I had going a while back with my setup. I would stall coming to a stop in both reverse and drive. I would stall after I hit the gas going in reverse. Also would stall while coasting around in a parking lot. My problem was the tune.

My problem was the tune. yes the truck was retuned for the jtube and tb and it was done years ago,it almost seems to get worse after its under load,if i get in to it a little bit when i come to a stop it gets all lopey like its ready to stall and other times as i am slowin down comin to a stop as i hit the breake the rpms will go higher instead of lower and the truck surges forward Quote Link to comment Share on other sites More sharing options...
zippy Posted February 25, 2010 Report Share Posted February 25, 2010 Have you had any work at all done on the truck recently? Quote Link to comment Share on other sites More sharing options...
