ok heres the summary.

1 month ago by burban had some intermentant stalling while driving. would cut out for a few seconds. then take right back off.

I replaced= cap,rotor,wires,plugs. nothing fixed it. then found broken ground strap. that seemed to fix it.

now one month later it will only fire up for about 5-10 seconds. it revs up then bogs down then revs up then bogs down and stalls.

I just put a pressure gauge on it and its showing between 55-62 psi. which i think 60 is normal. not 100%

anybody have some suggestions for me to try tomorrow.

i had somthing similar happen to my burb when i first got it, i accidentally found out if you rev it to about 5500 it will idle out haha i was a little frustrated

it kept happening and i only planned on driving it for about a month before i swapped out everything for a different drivetrain i had waiting

i ended up finding out that the PO had not properly attached the tranny to the engine and it was loose and was causing the knock sensor to send bad codes out
