My car is gradually declining to garbage...
When I turn the key the engine self test automatically goes on until I start driving ... I have a new EEC coming shortly.
Ok besides that problem, when I drive it, you can feel it hesitating, bucks under boost. Runs very rich, carbon buildup at end of tailpipes and back bumper - Black smoke when you get on the throttle.
The check engine light flashes on and off all the time but it doesnt stay on.
Things I have done.
Just replaced coil pack today - no change.
New O2 sensors, New Plugs/wires - 2months
New Cam sensor - 1month
My friend has an expensive scanner... shows real time data of the EEC... the o2 sensors usually are low voltage and often read "INVALID"
Here is the print out...
Ok these o2 sensors ARE BRAND NEW... I dont understand...How can I mess it up, I screwed them in and plugged the harness in... argh
I got a brand new knock sensor... don't see how that went bad... didnt put the new one in yet.
Observe number 18, Loop Status CLOSED.. what does that mean? Another test done 4 months ago read OPEN.
Guys im desperate here... I'll be willing to pay someone if they can tell me the correct thing to fix lol... PLEASE!
