Hi,

filled her up yesterday evening. this morning all of the sudden, engine light on.
just checked with diablo tonight:
P0133 02 circuit slow response (bank1,sensor1)
P0171 system too lean (bank1)
P0174 system too lean (bank2)
P1000 monitor testing incomplete
P2195 02 sensor signal stuck lean bank1, sensor1
P2197 02 sensor signal stuck lean bank2, sensor2

please, advice.
never happened before.
always on premium (c&l racer, diablo tune, flowmasters)
engine stalled 5 times on way home (7miles). goes from 1Krpm to 400rpm at red lights. sometimes stalled.

thanks.

 

First thing I'd do is reload the tune and see what happens, the lean codes are veryserious warnings, but some people reported getting those codes when installing hi flo exhaust systems. If you have more conservative tunes upload them to see if it helps. Check for air leaks in your intake system, MAF, also the fuel filter might be clogged.

 

Wonder if you could have bought some contaminated gas?

 

^^contaminated gas could def throw those codes. reload the tune, if still having trouble, return it to stock, replace the intake with the factory one and see what happens. then take it to the dealer if you're still having trouble. otherwise, crawl under your rear with a bucket and drain that gas.

 

Thanks guys, no contaminated gas on this side. ...
I found the problem: the elbow was loose on the TB. I noticed last night in my garage when I checked out the engine bay, that the cable on the elbow wasn't completely on it.
I pushed it back on and the elbow on the side of the TB fel off. So I loosened up everything, fitted correctly and adjusted secure (initial install wasn't done by my, but a garage).
I'm a little paranoid for now, hoping nothing else will happen regarding engine or so...
I cleared the error codes, started up and took it for a good spin. It's back to normal now.
