I do not do tuning, but do have the stuff to log. I am not sure what is going on. This problem has been posted by other people in the past. This has begun happening more, more recently. At first it was only when it was cold, very humid or raining. As soon as I give it any throttle it instantly pegs 10 on the AFR gauge and some times actually fuels it so much it breaks up. Then it goes away. I have cleaned the maf, because it does get some oil on it from the blower ( Procharger says its not out of the norm ) So any way what is going on here. 02's Bad MAF, vacuum leak, or other ? I unplugged the MAF and the truck did the same exact thing as if there was no affect, so maybe bad maf.. Any info is great.. Thanks.. BTW this is a pretty much ruff in tune that I never had finished up for reasons.

Thanks

 

Bank 1 02Sensor never drops below like 600mv.

Either that sensor is bad or your constantly dumping alot of fuel on that side. Your LTFT is 25.

You want your LTFT to be around -3 to +3 range or as close to 0 as possible.

 

Ok so headed to get new 02 now.. Hopefully it does the trick. It has been getting worse for some time, with these being orig 2003 sensors its a good chance it is done, going to change both of them actually. Thanks
