(tuning by Rick Crawford)
Car was running fine
> two weeks ago, disconnected battery, removed Vararam, cleaned filter and sprayed CEC MAF clean on my LS7 card style MAF
> allowed 2+ hours to dry
>reassembled
> drove next day and CEL came on
> hooked up HPT, P0171
> removed Vararam again and double/tripled checked all connections
> reassembled
> drove briefly, threw CEL (this time P0171 and 174 i believe)
> cleared codes
> out of desperation, disconnected battery for a couple of hours
>Bought and started Lucas fuel injector cleaning kit. still on first bottle.
> drove multiple times and it was fine
> last night took to grocery store down the street. THE CODE CAME BACK
I didn't touch anything else on the car. I can't believe its a vacuum leak. I've tried to find all the hoses to make sure nothing wiggled loose.
I emailed Rick but he is so busy, he might not ever get to my message.
I have some wild theories....I fried the MAF with that spray OR Rick tuned car long time ago and I kept sending scans and A/F gauge readings of 11.x and he kept leaning out tune till he said he has never cut that much fueling. Was my filter so clogged up that cleaning it tipped me over the edge of too lean and the computer is throwing the code now?
Any suggestions?
its times like these when I almost wish I had a bone stock Vette or something instead of a modded car. I love my G8 soooo much though.
