<DIV><FONT color=#000000 size=2>I've got like 7 relays, 4 new, tried rotating
them all around between fuel pump, MAF power, and burnoff. No luck. Back-cut
& soldered & patched in new connectors (relays & MAF) into the
harness, shrink-tube & all, still no luck. Swapped out TPS, adjusted all
different ways, no luck. I'm still open to suggestions though. It's definitely
getting funky signal, cause it's rough as all get-out when it trips. I've also
got a copy of the GM bulletins relating to TPI MAF's if anyone is interested.
Hey, those relays could still be squirrely, I've not replaced with GM genuine
parts or anything. Although the MAF supply voltage checks out during a
trip...</FONT></DIV>

<DIV><FONT color=#000000 size=2>Replace the relay's. There's a GM

they were ok.</FONT></DIV>

<DIV><FONT color=#000000 size=2><FONT size=2>I'm working with MAF still,
still having this weird problem of intermittent Code33(MAFHI). One of
these days, I'll figure it out. Must be loose wire somewhere, maybe in
the sensor, maybe something else loose or spikey. Maybe throw some caps
around & see what happens. Might like one of those heated O2 sensors
for the TA. Probably speed closed-loop approach with
