I have a 1994 GMC K1500 4WD with a 350 and TBI. I was trying to locate the
IAT sensor on this motor to attempt a resistor mod to see how it would
affect performance. However, from what I've read in the repair manuals and
seen in the schematics, I don't think this year/model uses an IAT or MAT
sensor. Additionally, the "books" say it was on '96 and later model GMC's.
Can you, the experts, confirm this info?
Please email me direct and firstname.lastname@example.org.
Any assistance is greatly appreciated.
Another question.....is there anything that one can do on the aforementioned
engine /vehicle to improve the performance without spending alot of $$? I
was considering headers, cold air intake system, and/or a performance chip
like the Hypertech chip. Any thoughts or advice from the groups as well as
actual mods that have been done on your vehicle would be appreciated.
systems and do have an IAT located just aft of the airbox.
Never used one (I use open-element style air cleaners) but the idea is
sound. For $24.99 is it sucks you could always return it.
Ya know, they're probably both about the same. The open element sucks in
more air but it's less dense, cold air systems typically suck less air that
is more dense, so the available 02 is probably pretty darn close. Besides,
at anything over 35 mph it's cool enough under the hood IMO.

those came stock on trucks with a 305 in them (both my dad's '90
C2500 and my bro's '93 C1500 had them) . my '88k2500 w/ a 350 had the
intake muffler on it. you can do the exact same thing with a 12"
piece of 4" STR35 drain pipe and some black spray paint.. total cost,
5 bucks. that how I run my '88 K2500.
