Hey All,
In trying to find out my van's stumbling issues.. i rechecked the fuel
pressure. Seems that i run at right around 30 psi during idle but if i
rev the engine.. or hold the engine at say 3000 rpm or so.. the
pressure will drop down to like 25 psi or so. Is this normal? Seems to
me that it should remain at 29 no matter what the load. This might be
why i am having stumbling on take off.. and is worse on hot days. Any
thoughts on this? The fuel pump is original and has 170,000 miles on
it.
thanks all,
jesse
