So, Had allsorts of codes but what I've actually comedown to is no boost so when it would down shift it would just start revving like it was in neutral. Got it home and now trying to remedy no boost (actually before the hood flew up and broke my boost gauge it would climb to 4#'s then...

Shifting fine sometimes now not locking up and acting like its in neutral Also having boost problems.....could the boost be throwing transmission into limp mode????? Please help desecrate....... Sent from my DROID2 GLOBAL using Tapatalk

actually we were thinking it might be a rouge fuel solenoid in the past it was like something finally got warm but now it just acts like somebody turned a switch on or off

Thought PMD do to the erratic behavior but usually they fail when warm not cold correct? Don't know about actual pressure but the lift pump runs good and ther is plenty of flow when cracking the top of the filter housing and the drain valve

My Burb will start sometimes (drove it all the week before last) then act randomly and not start or barely start. always seems when its cold, but gettin fuel and plugs are working Runs great when it starts Help please:mad2:

I'm Jumpin in with both feet The Burb could use some more fuel ):h

How do I know for sure I'm in limp mode I think I'm running in limp mode and I don't know how to check or what to do???

codes It reads the following 4 codes 17 18 35 43 starting a little better after the new fuel filter

New filter I put a new filter in yesterday after it quit:rolleyes5: I think I'm getting air from somewhere and I think I'm running in limp mode I cleared the codes last night havn't checked them since will check again today

If you clear the codes, do those come back? Is the SES light always on? we cleared the codes by disconecting the batteris they do come back If might be limp mode and not high idle. always @ high idle right now You probably have air in the fuel lines, bubbly fuel, water, or cloudy fuel...
