<DIV><FONT size=2 face=Arial> I realize many have this odd affect after the
engine is hot and shut of for 25 minutes and restarted the HTS or TS2 cools down
because the heads col down faster than the cylinders making th car run rich for
a while then it clears . </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> I got 7 gallons on gas june 28 and drove the
car maybe 6 miles and it was hot out 90* car ran fine. </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> Then on July 28th I drove 10 miles 40 MPH max
in 95* heat and the car ran as it has for quite a while . It sat for 20 to 25
minutes and when I started it and put it in reverse (auto trans) it seemed to
run a bit rough for a bit then the entire trip of 10 miles back I felt this
vibration in the steering wheel only when at a stop in drive foot on brake .
</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> The idle speed is the same and it seems to
run the same yet this vibration was not there before the trip back. It's an E
system Fuel injection and the only part I replaced was the MPS for the proper
one back in the end on Jan 2015 and filled up the tank. </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> Could this be caused by a FI plug terminal
that became loose . I ask because I never tightened any of them and feel it
would not hurn. I have have the MPS plug on and off the most and did notice last
time one of the terminals only looked like one of the sides you crimp was open
quite a bit. I never tested while running because you really can't and this car
has always had a vib in drive at a stop yet goes away as soon I let off the
brake and this new vib acts the same way in that respect it's just a new
vibration I feel in the steering wheel . </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> Like I said it seems to run like it did . The
only thing that seems to clear up the no load RPM instability at ldle is
unplugging the TS1 idle is unstable from 1000 RPM idle to 2300 RPM then responds
normally . I can't feel this in gear or driving . It also pops out the exhaust
if I speed up quick then let off the gas . If I speed up slower it may pop once
or twice. So the quicker I speed up while driving it pops more and I don't hear
this when TS1 is unplugged. It does have small exhaust leaks at the EMPI header
to the heat exchangers. This to me seems it's fuel lean or rich related
.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> Any suggestions would certainly help.
