okay so no vacuum leak. sprayed some ether around under the hood. no rpm jumps. im thinking maybe it could be a fuel restriction at this point.

FYI - It seems to have cleared itself up after putting some miles on it. Not sure what the issue was. I'll update if the issue come back.

So issue has come back

I've tried the following:

• new fuel filter
• new 703 injectors (did this as an upgrade do to leaking injectors)
• new oem tps
• new standard o2 sensor
• trans fluid level/color okay
• new speed sensors (speedo and computer) speedo one was broken
• checked for vacuum leaks

I had also checked fuel pressure which was okay. I forget the actual PSI off the top of my head.

It seems to only be doing it now once the engine warms up to operating temp. I'm starting to think its something in the trans since these 42re are known to have some solenoid issues. As of now no engine or trans codes are being thrown.

If anyone else has some ideas I'm all ears. As it isn't a daily driver I'm not in a hurry to its health restored. It would just be nice to not slowly accelerate like a loaded dump truck lol.

Thanks!
