I'm at the smog place waiting to get retested....
Last time I failed cuz of ma hfc and some of the monitors wernnt showing or not available...
I switched back to my stock cat and got a new maf...and the cel was gone...
Now I just scanned it and it still gives me system lean too bank..same code but with no cel?
Any ideas what it can be or any input on this...
Gracias...

 

system too lean can be a lot of problems. i'd do a seafoam on the vacuum system and clean the 02 sensors with MAF cleaner. i've never seen one fix for a system lean or rich code. did you pass?

 

i didnt know you could clean the 02 sensors how does that work hiwords has anyone had good results?

 

it just gets the carbon off the sensor. it was taught to me by a guy who's been wrenching for 30 years lol. i had a system rich code a while ago and those are the things i did. i guess seafoam the gas tank too.

 

ive injector cleaned my car seafoamed it in the gas tank and the brake booster seafoamed it also ive cleaned the maf sensor and the intake lol i still get 17mpg

 

Didn't even get to test it....ma lil bro callled. Me and had to pike em up from skool soo I just jammed.....
Now I foegot to add I have a lil leak in the hose by my boost gauge?
Could this cause the problem?

 

If you tapped the gauge into the intake port closest to the cabin, then that may be it. Thats your fuel pressure regulator.

 

Yea that's were. I tapped in....
But the leak is at the end of the line almost at the fitting to the actual gauge

 

probably got kinked and eventually tore through

 

Yeap probably....
Ima just plugg it for a while and see if that helps...
Ma silicone vacum hoses r being ordered soon...
