Thanks for the ohms and volts chart. I checked both sensors, checked out good. Fuel pressure is 59PSI. I cleaned the air intake sensor, but nothing has changed in the way it runs. Took it for a 10 mile run, when I accelerated (under a load) it would kick and buck as if I turned the key off, then back on. Probably 6 out of those 10 miles, the engine runs fine. It is as if an injector or coil is bad when it drops off, but it is like it is all of them simultaneously. At idle, it may run fine for 2 to 3 minutes, then just die. Starts right back up. I checked the wiring harness for maybe problems there, but nothing noticeable. There is no consistency to the problem, hot/cold, high/low rpm, acts the same. No codes are present, no check engine light. I have access to a snapon scan tool. Scratching my head. Would a fuel pump relay be intermittent to cause the engine just to drop off, shouldn't it slowly die if it were the relay? I am puzzled.
