<LI>This step will determine if Code 33 is the result of a hard failure or an
intermittent condition.<BR>A Code 33 will set if:
<UL>
<LI>MAP signal voltage is too high (low vacuum)
<LI>TPS less than 2%
<LI>These conditions for a time longer than 5 seconds </LI></UL>
<LI>This step simulates conditions for a Code 34. If the ECM recognizes the
change, the ECM and CKTs 474 and 432 are OK. If CKT 452 is open, there may
also be a stored Code 23.</LI>

<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>
