Replacing the Wax-Type Fast Idle Solenoid (Z24i engine) - Page 4 - Infamous Nissan

I have the 87 2.4l. does this apply to that engine.

YEPEE · 09-25-2017, 11:08 PM

YES it does

I know I'm replying to quite an old post but can anyone verify if this is for an '89 Z24i engine?

Yes that’s the number for an 89 Z24i

Thanks! I had already ordered it but I was asking to know if I should cancel my order before it shipped. Had a smog test today, emissions passed but idle was too high for them to test timing.

My part came in and I'm going to put it in today. On page EF & EC 214 of the FSM it tells me the clearances between roller and cam that can be measured with a feeler gauge.

My truck failed CA SMOG test on the functional test because of too high of an idle so the timing couldn't be tested. After installing this thermo element I still need to adjust the idle screw but I have no tachometer.

On page EF & EC 215 it tells what the idle speed RPM should be at but I could use some help. I'm trying to track down a place I can buy a multimeter locally that I can hook into the ignition system to test the RPMs. Which wires would I hook the tool up to on the pickup? Any of the spark plug wires?

Edit: Maybe I should just install an outboard tach...

That should just be "normal idle speed".

Basically, when you switch on the A/C, the idle speed should increase to compensate for the extra load.

I'm not to worried about the A/C stuff, I don't even have one. The issue is I tried to get it smogged and my idle was around 1600 rpm. They needed it closer to 800 for them to do their timing check. I have no tach to tell me what the resting RPM is being adjusted down to. I guess I'll have to do it based on sound.

Are these things no longer available any more?
