<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
bulletin on this. Terry, Kev just replaced the relay's on his new ta
and it fixed, this after he looked at them under a microscope and was
"SURE" they were ok.</FONT></DIV>

<DIV><FONT size=2>Isn't the max maf airflow table used for throwing a
Malf 33 (MAF too high)? It's RPM VS AIRFLOW.</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 headers.</FONT></FONT></DIV>
