Totally normal, expected even, good for you.? Why?? ECU has been used to and made micro adjustments to compensate for dirty cloggy IACV.? So it's running high with new cleanliness.? Solution:? give it time, like 20 startup shutdown cycles.? Each cycle, ECU will make adjustments, and gradually get back to normal.? Don't mess with any adjustment screws....let the ECU do what it is supposed to do.? Still, 2000 RPM cold idle isn't bad so long as it drops down to the 1000 RPM range.? Removal and thorough cleaning of Throttle Body should also be done at same time (new gasket to manifold too), everything gets gunked up and sticky over time.? Wouldn't hurt to also replace PCV valve and clean out interiors of rubber hoses connecting.? Do it now and you should be good for 100K miles of smooth performance (including better MPG, lower Smog Test numbers, peppier motor.)

Hi!
I cleaned out the IAC valve on my EJ22 swap in my 1990 Westy and am seeing an increase in idle RPM.
At cold start, it goes up to 2000 RPM in Park. After she warms up, she drops down to 1100 RPM.
What should the idle normally be set to since this seems high?
?
Thanks!

The stock VW fuel pump provides plenty of volume and pressure and works seamlessly with the Subaru engine.
Your 2.2 doesn't use any more gas than the 2.1WBX.

Did other folks swap out the fuel pump when they did their conversions? If so, what other components did you swap out in order to keep wup with the suby engine?

Re: gas tank emissions monitor isn't setting
Gary,
Which exact plate are they trying to get? There are numerous different plates in Nevada for older vehicles (classic vehicle, classic rod, old timer, etc) and they all have slightly different rules.?
I’m familiar with classic vehicle and classic rod registration here in NV. For both of those you will not need to smog unless the registration has been red-tagged by the emissions lab. You just need to not have a failed smog within 90 days of registering the vehicle and hold classic vehicle insurance.?
If you’ve already run by the emissions lab and have been red tagged, then you will need to address the problem.?
Connor?

The smog testing in Oregon entails the referee sticking a sniffer wand up the vanagon tailpipe and analyzing the readings to ensure that the vehicle is burning at least as clean as the standards set for an 86 vw engine.
Am I close to answering your question??

It's a 2004 EJ25 being put into an '86 (full).? The shop is saying that it's done - except for this problem.

This is for Nevada - it needs to pass smog because they're trying to make "historical vehicle" registration for show (aka parade) cars only.

Re: Warren’s Conversion - Engine Bay
I got several things done in the engine bay today. ?First, mounted the RMW stainless bracket for their aluminum coolant tank. ?I mounted it approximately 1/2 inch below the tab as recommended.
?
?
Then I connected the silicone hoses to the coolant pipes that run from the front, with the longer of the two on the inside pipe. ?I’m not sure whether there are any additional changes to make the the hoses running front to rear. ?RMW’s instructions make reference to switching heater hoses around, but it’s unclear whether that only applies to syncros or whether it also applies to 2WD Vanagons. ?I have a call in to RMW for clarification. ?Hopefully I’ll learn something tomorrow.
?
?
A little progress every day.

Good call. I’ve read that the braided flat ground straps are best. I’ll try to locate several (extra intake ground as well).?

Re: Warren’s Conversion - Engine, Transmission, and Starter
Run a ground strap from the alternator and the starter ground to the chassis while you're at it.

Wayne, thanks for the link. But in that thread, if the ECU was constantly
rebooting, then the car would be bucking like hell, which it’s not. It runs real
smooth.
?
It may be one of the 2 other relays (fuel pump and starter) that are next
to the ECU. Luckily, I have 2 relays that I can use to replace them. I’ll update
the thread after I do that tomorrow.

If it is the ECU it could be a bad battery. How old is yours. Have it checked
out. Try another battery.

Likely to be a relay under there as the ecu has no moving parts unless you’re hearing electrical popping in which case you’d want to figure that out really quick I think?

I've been trying to find out a lousy chattering noise from under the bench seat for a while now, and think I may have found it.

I have a 1990 Westy with an EJ22 conversion. On cold start, there's no noise from the back, but after the engine, then I start hearing a chattering noise. Thi happens at idle and low acceleration from idle. It sounds like it may be coming from the ECU. Has anybody else had this problem? Is this a way for the ECU to tell me it's about to fail?

That black and orange connector might be what connects to your O2 sensor subharness for pre and post cat O2 sensors.
