I just cannot believe all these continue to happen at the same time by chance - do there must be a connection (or a connector?, ha) Revved to ~4000 RPM but vac performed as expected, smooth and up & down. One old school test I performed was manifold vacuum it was not exactly steady at idle, but varied +/- maybe five pounds.
I sprayed first a little then a lot into the tube and finally got a slight reaction. I then took off the fuel pressure regulator tube and it had virtually no effect. it took a surprisingly large amount to affect the idle. Then I thought I better verify its effect, so I disconnected the vac tube from the B/W check valve and sprayed into the tube going straight into the manifold (I guess). I had replaced the vac lines to the EGR valves, one was broken off open, but I suspect I broke it when I was leak-hunting.įWIW, I liberally sprayed the manifold/block juncture with CRC MAF cleaner without result. for each, but I searched last night and no luck.Īlso, do all these cars (4.2s) need the EGR Adaptation MP talked of in the past? Trying to run down codes including a trail to fuel pumps and would love to log pressure, pump status, etc.

Thought I'd found it by searching Bentley but only on the V10 and another production code (=newer) engine. Is there no fuel pressure sensor? Found the blocks where fuel pumps status is, will try to post a log ASAP

You can still do that with propane, right? I've got a big full tank that won't connect to my grill. Naturally, and as usual thanks in advance for any help. Bosch doesn't send out defective ECUs right? I fixed the EGR lines and airbox since then. Can't find much info on it.Īnother thought I'm entertaining is to swap the old MAF back in.
I know there is a common connector where these converge that's broken! Or at least they are related somehow.Īlso that big pucklike throttle control valve makes me nervous. Once, the car stalled without the last two, but usually they are set. It only occurs at or near idle, usually after driving at 45-55 MPH for 5-10 minutes. The first two codes are almost always there.Īnytime the 16487 MAF P0103 occurs the car stalls. P1857 - 000 - Error Message from ECU - IntermittentĪddress 03: ABS Brakes Labels: 4E0-910-517.lbl
