big score on the trans being good!
I had a feeling, but cannot express what a relief it was after starting it up and realizing it was able to go into reverse with the engine running.big score on the trans being good!
The car has no check engine light, but decided to go out on my lunch break and see what I could find.
Stored Codes:
P0113 - IAT Sensor 1 Circuit High (Blow Through Style MAF with integrated IAT; have MAF cleaner just need to pull it and clean it)
P0352 - Ignition Coil A Primary/Secondary Circuit (These may have been related to when I forgot to plug the passenger coil back in?)
P0352 - Ignition Coil B Primary/Secondary Circuit
P0412 - Secondary Air Injection System Switching Value A Circuit (No emissions on the car as far as I can tell)
P0135 - 02 Sensor Heater Circuit Bank 1 Sensor 1
P0155 - 02 Sensor Heater Circuit Bank 2 Sensor 1
Pending Codes:
P1504 - Idle Air Control Circuit (May have been related to pull the plug while running to see if idle changed, regardless new IAC arriving Friday)
P0125 - Insufficient Coolant Temperature for Closed Loop Fuel Control (Low Coolant sensor was unplugged; forgot to plug it back in)
I'd love additional suggestions of what to check.
I just did this maf with the IAT integrated. I did have the harness for my car. If I didnt have it all wrapped up id post a pic of mineWell found something that definitely wasn't helping anything and I think could possibly have effected the exhaust tone.
The car has a VMP blow through MAF setup with a newer style slot MAF. I assumed it was using the integrated IAT, but after reading through the VMP website that's only for 01+ cars, the 96-98 has to have a special harness soldered in for that. Realized the IAT has been unplugged this whole time. I've tried to research what this would do, and it seems that it causes the PCM to pull timing and puts the car in open loop with a lot of fuel as the PCM assumes the coldest temp for fueling to prevent detonation.
Hoping this is a productive weekend once this is fixed. Plan is to install the new IAC and get the air intake attached now that the T-Bolts are here. Get the IAT sensor plugged in, reset the codes, and then fire her up. Will report back once that's done.
I may mess with that in the fall, as it would be nice to have it part of the MAF as that's post blower/intercooler and will provide better readings... but for now I'm just keeping my fingers crossed that this was my issue.I just did this maf with the IAT integrated.

I'm literally rolling laughing, I hit my head on that bike and curse at least three times whenever I work on the car. This used to be the spot for my 4Runner and it was never an issue. The third car spot is taken up by my sons ride-on toys, and I will likely move the bike there this spring once I finish cleaning that side out.How many times you hit your head on that bike?
I wish I knew the older car wiring harnesses.
As far as the O2 wiring - should be pretty easy to look at the exhaust manifold/header before the mid pipe and see the O2 sensor sticking out and if its plugged in or not. I feel like you'd have more than one code if it was unplugged though. You could also log the front O2s and see if you actually have signal or not. If the rears are turned off they might be unplugged as well
So I've looked at that chart and while I never picked up on the fact that Super 44 is a Delta Flow, and the Original 40 series is not... I don't know it sounds quiet compared to my old setups even though it should be more aggressive per the chart?
