My car has been running great and this morning all of the sudden... I had driven about 2 miles to my friends workplace and hung out for about an hour or so. I went to leave and when I pulled out into traffic it started bucking like a horse. I let off the gas and was able to limp dick it back to his store. I looked under the hood for loose hoses or lines. Nothing. I limped it back to my house and further inspected everything, even the spark plugs and plug wires. Nothing. Then I see it. I look over at my SAFC and notice that my correction % is dead 0%. Never moved and still isnt. Everything else is though, my rev, knock, and throttle all are normal and move with acceleraltion but nothing for the correction. Whats that about?

 

it wouldnt hurt to make sure all your connections on the afc are good.

 

when i bought my car, it already had the afc connected. for about a year, i had the worst idling and acceleration problems. turns out, the tps connection to the afc was messed up, and then from the afc to the ecu, the wiring was all messed up. so i was getting readings that i thought were normal, with no apparent problems, yet the car ran like crap. it runs great now.

 

The guy who put it in for me is incredibly respectable and knows his shit, so I cant even think for a second that its anything he did, plus Ive had it wired in now for over a year. I looked over the wiring myself though and nothing stood out. All the wires are still in my ecu and there is nothing wrong with the harness wires either. Any other suggestions? I hope so.

 

ecu could be going bad!! maybe

 

people do make mistakes though, even the best. always good to double and triple check everything.

 

+1 nobody is perfect.

 

drew has worked on ur car, rite?

 

yeah Drew hooked up my afc. btw does anyone have one I could just plug right into my harness so I could either rule that out or in? that would be a huge time saver I think. At least that way I would know if it was my head unit right away, you know?

 

i have a safc 2 i have had it for like 6 or 7 months now and it works great i hooked it up myself so maybe i can look at it for you
