<BODY bgColor=#ffffff>
<DIV><FONT size=2 face=Arial> A while back I tightened all the FI
connectors , the only one I didn't was TS1.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>. Before I did there was an erratic miss @ idle and
lot's of popping out the exhaust ( the more I opened the throttle and let off
the more pops I would get & I could get it to pop in neutral auto trans just
by giving it gas and letting the throttle close ) . </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> Now it does have much less of an erratic miss
in neutral @ idle and less popping which I hear out the Empi single muffler
quiet pack and header. </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> Today it was hot and I drove it further 10
miles and also hot 85* yesterday and only drove 2 miles
that day and I heard the popping , not as much as before so it seems higher
temps affect this. </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> Here is the odd thing yes the empi header
does not fit real tight especially on the right lower heat exchanger yet it's
been like that for a very long time and didn't pop at all. The header fits tight
to the heads and I have good metal gaskets on all 4 head exhaust ports.
</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> I realize air in the exhaust can cause a pop
, it's not loud like a backfire gunshot , it's just pop-pop-pop-pop . I also
know TS1 is an air temp signal to lean out in addition to TS2 . </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>[ The only way the popping and that erratic
miss stops is if I unplug TS1 . ]</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> The TPS works as it should and looks good
inside and checks out with an ohm meter and the car has good pickup . Even after
it's hot 180* oil temp it always starts right up , last I checked TS2 was 2000
ohm @ 85* F don't know what it reads hot.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> Does anyone have any idea what I'm over
looking here? </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> I know TS1 drops in resistance as it warms up
and unplugiing it offers a richer mix by 5 to 10% so I've read , what I'm not
sure about is does it lean out the mix as it's resistance drops?
