Need a little more info on replacement engine. Does the current 1fz have the secondary air injection from the 94 engine? Are you running a vacuum fuel filter with 1 port or 2? Another question, if you unplug the 3 pin alternator connector, does the idle come up? The new vane air flow meter is it a known good OEM or a so called Remanufactured or god forbid a chinesium knock off?
Are you referring to the PAIR system on the ‘94? All that has been deleted. I have not tried unplugging the alternator connector but I will and report back. The replacement AFM was supposedly good and is a used OEM part. But I’ve had 2 people now tell me to try another one. Guess I’m on the hunt for one to try out.
Vacuum fuel filter? It’s the factory filter under the intake.
Yes, Im referring to PAIR. Guessing you used the exhaust manifolds from the donor engine in lieu of block off plates. Vacuum fuel/gas filter screws into the top of the intake (next to PCV hose nipple) and has a hose that goes to the fuel rail. 93-94 has 2 hoses whereas 95-97 has only one. Did you use the intake manifold from the donor(97) or the original(94) engine?
Gas vacuum filter Location 95-97 version, 93-94 same location but has 2 hoses going to it.

Any vacuum leaks at the vsv valves, lines under the intake? Have you unplugged the alternator connector yet?
Will have to wait till tomorrow afternoon when I can get under the hood of my 94 beater 80 to see the vacuum diagram as it’s original engine has too been replaced with one from a 97. The additional port is for the PAIR at the end of the line but I can’t remember what is in between.
Hi, So did you drop the old gas out? Did you check the fuel pump and sock ? Also try non-ethonol gas. Mike
Hi, Have you pulled the codes? Mike
So I pulled my VFM to check E2 & VS pins while opening the plate. Ohm values all over the map as the plate is opened. 2600 when closed. Jumps to 3000 as I open it, then back to 2700, then up to 5800, back to 2700, and when fully open only 780. According to the FSM, I think it’s safe to say that this VFM needs to be replaced. Should be a smooth increase across the plate instead of sporadic. @offr0adlim0
Good deal. Now the real fun starts. Hunting down a part that was only used for 2 years on a 1fzfe in the states.
If you haven't already searched it, there is an option a few folks have tried from the 94-98 Camry. Search in here for Camry and you are likely to find it.Yeah I spent a little time on that this afternoon. Not gonna be fun. Reman supply is dried up, China knockoff looks sketchy at best, and unknown condition used units seem to be sparse and higher than pterodactyl tits when you do find one.
Any tips to cleaning the IAC. Pulled mine and wasn’t sure what to look for. Luckily years ago I replaced the hardware with cap screws. I wonder if the O-ring gets old and fails which makes the problem worse.Based on your description, I would check in the following order:
I know you've already done some of this.
IAC Valve clean / replace
MAF
Wiring Harness by EGR
Unfortunately, you have already touched and messed with so many things, you're having some unknown conditions and you feel like you've already done it all.
Try to get out of your own head an look at each one from a new aspect as if you are helping a friend and have never been exposed to it. Outside the box.
Make sure you have the AC button shut off.
Make sure all your ground cables are installed. There are at least (6) in the engine compartment.
Good Luck!
I don't have any tips, as I have not done mine. All I can offer is to search in here, as I know others have done it and posted about it.Any tips to cleaning the IAC.
