i have a 2003 4.0 5 spd edge that stumbles, shakes and acts like its going to stall untill 1600+ rpm. it has a new coil, newer wires (10k miles) new plugs. the fuel psi at the rail is 62 psi, compression is 160psi on all cylinders, there are no codes or lights on. i am completly stumped. i use a spark tester all plugs have spark. it has new intake gaskets, and a new pcv elbow. anyone have any clue on what could help?

 

Fuel. If u have compression and have spark. Must be fuel. Sounds like a misfire. Check makesure all connectors are tight on the injectors. Make sure there all firing

 

What kind of wires? Watch them at night. Really sounds like wires.imo. Any engine light for a cylinder #?

 

Didnt have a cel its fixed found the problem there was more water in the tank than gas damn gas stations

 

Haha. Happened to me a few times. Send me on a damn goose chase

 

^ agreed lol so simple yet pisses you off cause your stumped.
