Re: Weird 4A-GE idle problem

Hmmm... it seems that your AAV is operating much as expected except for the idle dropping to 500rpm sometimes. As totta crolla points out, when you add electrical load a small solenoid valve should open to allow extra air into the manifold via one of the small spigots on top of the throttlebody. Thi...

Re: Hesitation @ lower rpm

If you have an AFM, check that the flap inside is free to move and not binding or
sticking at low throttle openings.

Re: Weird 4A-GE idle problem

Hmmm... my bad :oops: I think that I read your post too quickly, and didn't pick up that your engine is actually doing the opposite to what it would if the AAV was blocked. To be clear; if the AAV is working the engine idles high on cold start and tapers down as the engine warms up. Normal is 2200rp...

What you describe are classic symptoms of how an engine behaves if the AAV (ISCV by another name) is not working. If you have have placed the whole valve in boiling water and seen that it moves 3 or 4mm, then the next thing to check is if the water from the coolant piping is actually circulating thr...

The remaining question is, was it oil volume? Or oil pressure? (Inside the puck) Optical sensors can be affected by anything that obstructs light getting from the emitter to the receiver.

Remove the throttlebody from the intake manifold and point it towards a light source as if you were trying to look down the throat of the throttlebody. Then open the butterfly slightly. You will see a thin crescent of light appear on the edge of the butterfly. Because of the high contrast you can ea...

Re: 20v 4AGE ST Misfire/miss.

Just googled to see what was inside that "puck" and it uses optical sensors.
So if you have oil getting flung around inside you probably have your answer.
A bit of printed circuit board cleaner spray should clean that up OK.

Re: 20v 4AGE ST Misfire/miss.

If you slowly increase the engine rpm, say in 3rd gear on a level road, can you reach high rpm with little or no misfiring ? That is, does engine load affect the onset of misfiring ? If it does, it would be worth trying a set of plugs one heat range colder. A cheap set of basic NGK's would be fine.....

Re: Need help identified this

The vacuum lines under the throttles do not have any connection with the A/C. I am reasonably certain (but open to correction) that the AE111 does not have a separate A/C idle-up valve. The ECU monitors the idle speed and uses the ISCV to compensate for the extra load when the A/C turns ON. If this ...

Re: 20v 4AGE ST Misfire/miss.

I have never looked at the AEM software, but there should be an enrichment table that adds fuel when the engine is cold and fades out the extra fuel as the water temp rises. It should be zeroed by the time the engine reaches normal operating temp. I would expect that when your engine is fully warmed...

I like it when someone tries to be different :) Got a pic of your setup?

Probably depends on the size of your turbo. If...
