Did you ever get these mounted on the car? Pics please!

actually, i found a break in one of the coil wires which caused the spark to arc on a nearby ground. this caused the slight hesitation and miss at idle. also making adjustments to the TPS helped a bit. how are things in the PI?

I see you have a MAF housing, do you have any MAFs for sale?

well, i tested the MAF/IAT and the resistance is a little odd. at 68F it should be 2-3k ohms, im getting 1.5-1.8. at 176F its supposed to read 0.4-0.7k ohms. when I heated the MAF with a hairdryer it read 0.6-0.7k. Does it really matter if im at 1.5k ohms instead of 2-3k ohms? i also tested...

Im thinking the oil probably comes from the PCV? It recirculates the crankcase pressure back into the intake. might be time to change your pcv valve.

I dont think its a tranny issue, but i'll give that a shot. Swapped the Fuel pump ECU and no difference. Im gonna check the IAT on the MAF and see what the resistance is. Maybe its getting some screwy readings.

20 degrees c = 68F 60 degrees c = 140F 80 degrees c = 176F

I took a look in my SC400 manual, not 100% sure if they are the same. water temp sensor: 20 degrees C = 2-3k ohms, 80 degress C = 0.2-0.4k ohms intake air temp: 20 degrees C = 2-3k ohms, 60 degress C = 0.4-0.7k ohms Not sure what EGR sensor you were asking about.

well the coolant temp sensor was a waste of $25. Next up: Fuel pump ECU.

im not getting any CELs and my MPG is decent. My most recent tank got 21.5 MPG mixed highway and usually i average between 17-20 MPG depending on my right foot. Im truly stumped... I would think if my car was running extremely rich, i'd be averaging really crappy mileage. Also, my car runs...

is the cold start temp sensor the same as the ecu temp sensor? i was thinking about just swapping them around, but the part is about $25 USD, so i'll probably just buy one and give it a try.

I've done a search and im pretty much stumped. Most of the threads I have read had told me to replace most of the items i've done already. So far I have replaced: -fuel filter -cap/rotors -NGK plug wires -NGK platinum plugs -New ignition coils -swapped ignitors -seafoam treatment -cleaned pcv...
