When you click on links to various merchants on this site and make a purchase, this can result in this site earning a commission. Affiliate programs and affiliations include, but are not limited to, the eBay Partner Network.
Also you can find used wiring harnesses on eBay for not a lot of money, not to mention rebuilt fuel injectors. I'm thinking it's easier to fix what you got instead of rebuilding with dated technology.
Well got my hands on a snap-on computer it can read but not change anything. I still reading -38 temp in Florida. No check engine but stored codes on both computer ( p0158, p1179,p1177,p0451,p1317) on top of watching live it says road speed is anywhere from 1300 mph- 20k mph. Tried unplugging seed sensor didn't change anything. So now what I don't have use of computer for long just this weekend. We spent half day chasing wires. I can unplug sensor with no change except maf kill the engine. Put used computer on and get close to same reading.
