I've done all but the wiring harness. I'm leaning toward maybe a short or broken wire in the vaf harness I'll be tracing it in the morning.

Well, this morning I started examining the VAF harness. I know I found a problem, hoping it was the problem. The white wire (was in a hurry to get to work so didn't get to reference the Haynes as to what it goes to in there) was broken off where it is crimped into the contact. I pulled the contact out of the plug, opened the crimp up, stripped a little wire, then recrimped it and reinstalled the contact into the plug. On the drive to work this morning I revved hard from every stop to see if it started doing the stumble thing any, and it never did. So I'm hoping that fixed it. Anyone know what the white wire goes to? I'm wondering if, with it broken, the computer was cutting the fuel at a certain point, but cycling the key might switch it back into "start up" mode where it would ignore whatever signal it was getting from that wire and run ok for a couple mins. Still find it strange that not once during all this did it throw a CEL (the bulb does work though). Idk, I just hope that this will get me a couple hundred more miles out of each tank I'm going to fill it up in a bit so I can start a fresh MPG check.

Just found that wire in Mitchells. It is listed as the "VAF" input to the ECU. The other two wires to the ECU are green/black (listed as "VAT", intake air temp I guess?) and black/white (listed as "VREF" I'm assuming the 5V reference that the VAF uses for the two sensors?). So if that white wire was broken or barely making contact, it would make sense that the ECU could be telling the injectors to do some really strange things lol.Last edited by htchbck; 10-24-2011, 07:31 AM.No festiva for me ATM...Comment

Well, the problem hasn't returned, and I put about 40 miles on it yesterday and the fuel gauge hasn't moved either (before it would be dangerously close to 3/4 by the time I hit 40 miles). Drove Green Car in today, but I'll be picking up Chuck after work before I head to Papa Johns so hopefully I'll have enough miles on it by the end of the night for a decent MPG reading
