Re: AC Idle Up Connection Plug

I installed a IACV delete plate and resealed the intake manifold and my idle is much lower 1600-1700 but my idle is surging now. When I turn the throttle idle adjustment screw fully in my idle doesn't go lower but when I turn this screw out idle does go higher... think i still have a vacuum leak? I ...

Re: AC Idle Up Connection Plug

Looks like the intake manifold to cylinder gasket is leaking somewhere, I sprayed carb cleaner in the area and the engine revved up. Totally bummed because I used a Toyota metal gasket and torqued all bolts like the service manual said. hopefully this is the cause of the idle problem I have.

Re: AC Idle Up Connection Plug

Update!! So I cleaned the throttle body and plugged all the vacuum ports... looped the coolant lines so there's no coolant to the throttle body. On a cold start my motor revs to 5k!! when I unplug the A/C idle up port revs drop down to 4K. I noticed the idle adjustment screw doesn't change rpms at a...

AC Idle Up Connection Plug

I deleted the PS and AC so I capped all the throttle body ports but I noticed there was a loud vacuum leak from the ac idle up connector... I never capped that because there was not the obvious metal tube sticking out like the PS idle up ports it’s just a open hole. Anyhow when I put my finger over ...

Re: 4AGE 16v no injector pulse

I did not try to crank it after installing just the efi main relay. I swapped both parts then started the engine.

Re: 4AGE 16v no injector pulse

Checked the AFM like the service manual said and the resistance between pins was really off spec so I ordered a remanufactured AFM. Also got me a new EFI main relay and battery. Man I hope this works. I’ll keep y’all posted hopefully this helps someone out with similar issues.

Re: 4AGE 16v no injector pulse

:evil: So tonight went well with the corolla... well kinda. :) I verified I am getting pulse to my injectors, I was using my Noid thingy incorrectly. I adjusted my TPS and my code 7,11 is gone now!!! But it still isn’t starting I checked the following tonight. - resistance checked out ok on my distr...

Re: 4AGE 16v no injector pulse

I do get fuel related action through the cold start injector(it fires up then dies after a few seconds). I can't get the injectors to manually click through grounding the #10,20 pins. What is the order of operations on manually pulsing the injectors? Cheers jonde86 you are keeping my ae86 drive aliv...

Re: 4AGE 16v no injector pulse

I’m very curious cause My injectors arent pulsing. I just sent my ecu out for a bench test and repair. Hopefully it wasn’t a waste of time and money. Thanks jondee

Re: 4AGE 16v no injector pulse

With the 10 pin ecu plug disconnected and all the injector plugs removed you should still get 12v to one side of the injectors through the resistor box right.... that is what feeds 12v to the injectors right?

E21,E2 ECU connector ground locations

I bought a 1985 corolla gts smallport swap with wiring issues. I verified 40 psi at the fuel rail and 12v to the injectors with all four of them disconnected. I am getting spark, but my car won't start... after reading a whole lot Im guessing its a ground issue or the ECU is bad. I have checked cont...
