well the only things like oil, filters, plugs, brake cleaner, shop towels, etc that i dont have im getting when i pick up my gaskets

i've got my moms car i can borrow for a run into town if need be, but i'd like to avoid it because the closest store with any import parts is 50 miles away

thanks for the advice guys, i hope it goes smoothly after all the ---- i've gone through to get this far

seriously take off the throttle body before dropping the engine in, i've done 3 swaps and broke the TPS twice, the other time the plug got cracked. it's only four bolts.....

im putting the head assembly in seperate unless i have enough help so i can rotate the motor onto the tranny easily enough

TPS come, and TPS go... but mis-plugging IAT and purge solenoid plugs on OBD1 cars usually results in fried IAT, fried ECU, or a combo of the two. I have spare TPS, but for some reason I can't keep IAT or ECUs in hand... unless you want to count the seventeen crispy Q31'd ECUs in my parts bins.

She may seal fine short term, but if you've ever purged coolant into the reso you can consider the headgasket as good as blown. You are living on borrowed time. Are you guys as super ------- hot up there as we are?? You can set up Crome to yank extra timing as IATs rise up... I was logging 120 degree IATs on the Black Car saturday night, and she usually hits 10 degrees over ambient at most any other time of the year.

This is when I ask, what you're smokin. Plugging the Purge (or IACV since they are the same) plug into the IAT will not USUALLY ---- it up. The resistance of a "cold" IAT is around the 3K area and a 12volt signal across 3K does not have enough current to mess the IAT up. It will however, fry if you swap that ---- when the IAT is nice and toasty like say above 100 degrees F. So normally this does nothing and the time when it usually gets swapped aroung is when the engine is cold.


JD is right though, it does happen.

I'm smoking a basic electronics text.

No, they aren't the same. At all.

IACV gets a pulsed ground. Purge solenoid gets a steady one that has a certain amount of current flow guaranteed due to the nature of a saturated transistor... IAT is a fraction of a watt rated piece that normally dictates it's own current consumption based on a 5vref, and the ECU just monitors voltage dropped across it passively. This is why purge<-->IAT swappage likes to fry the IAT. IACV<-->IAT might, but I see a much smaller chance of doing so due to the nature of the beast, and that IAT live for a minute sometimes mis-plugged to purge.

The seven times I was standing there when some n00b did it, after being warned, the engine was dead cold. Four of those times the engine hadn't been started in weeks to years... re-read about how transistors draw current without regard to voltage.

Never done the purge into the iat but will keep an eye for it now


Jd always bringin new info

Tom-Guy

Actually, no, I'm just here to impress 17-23 y/old men.

Sorry, I meant that the plugs are the same.


A saturated transistor only draws as much current as the voltage and any external resistors placed across CE

Tom-Guy

I wonder what happens to an IAT when you start dropping current it wasn't designed for across it? Snowball lowered resistance higher amperage effect?
