Hello everyone,
Within the last week, our '98 jetta has developed an intermittant problem with losing power while going up hills and cutting out (as if going into limp then back to full power many times rapidly). On the flats, if you stay light on the throttle, you can maintain 70mph, but any more than throttle than that, it starts cutting out again.
Fault code:
00550 - Start of Injection Regulation
Things i've checked:
N-108 resistance is 16.3 ohms (in spec)
G-80 resistance is 83.6 ohms (in spec)
Basic settings measuring blocks:
043 ~048 000 009 101 204 075 142 164 ~140
(glow plug light comes on when in basic settings). Timing graph shows timing about 1/3 of the way above the middle line.
MAF specified: 250
MAF actual: ~465
Things that are new/replaced recently include the TB (replaced it myself about 5k miles ago), all the vacuum hoses (except the blue one and one in ECU). We are running B99, and it has been cold, so gelling could be an issue.
I am ordering a couple fuel filters, but want to know if there are other things i should check in the mean time. I'm hoping that the fuel filter will solve the problem as it does seem to be a load related problem (the problem gets worse on extended climbs, and temporarily goes away after a long downhill run).
Are there any more suggestions? Are there obvious things in Vag-Com that will help point to the answer (i'm still trying to figure out that wonderful tool).
Thanks,
-Damon
