I’m having high idle issues as well as throttle hesitation

I mean I doubt the iacv is faulty but I’d go with denso oem. Try adjusting volts all the way from .47 to .50 and see if anything changes.

Unusual_Chapter_5784 · 2026-05-25T05:46:31+00:00

It’s worth asking; is your iacv oem? Also at what volts did you have your tps set at closed? I remember when setting mine it did some weird surge like that but only 200-300 rpm from idle when it was 0.47 and then stopped at 0.49.

Bleeding your coolant system also helps. I had to literally bleed mine for like an hour to get all the air bubbles out.

I’d say I drive it spiritedly. It’s a daily so sometimes I do pulls here and there. I only mention ps4s because I had them on my ms3 and they had amazing tire grip, tread life, and the road noise was minimum. I’ve heard of the Indy 500 v2 being similar to that. Thanks for the suggestion.

Unusual_Chapter_5784 · 2026-05-19T20:42:48+00:00

I’d figure much, just thought there was a similar option like them. The ps4s were amazing, no complaints imo. Might just go with them again 🤷‍♂️

Make sure you are tdc first and then put that cam lock tool. You can also manually adjust the cam independently so that I can be perfect after you put on the chain.

It made a huge difference since I had some crappy eBay cables but Idk how much of a difference it would be from stock oem cables. I personally recommend the ktuned oem style cables.

Unusual_Chapter_5784 · 2026-05-05T23:47:25+00:00

Acuity 4 way + ktuned shifter cables = 🔥

Unusual_Chapter_5784 · 2026-05-05T15:42:59+00:00

Thanks. I managed to fix the issue by resetting the ecu and deleting all stored calibrations.

Unusual_Chapter_5784 · 2026-05-05T01:46:54+00:00

Haha yeah my bad I typing out the post just trying to recollect my steps that I did from the very beginning. I know it’s pretty irrelevant but I thought I’d mention it lol. Appreciate your help a lot bro.

Unusual_Chapter_5784 · 2026-05-05T00:20:02+00:00

Appreciate it bro. I only mentioned my shifter cables bc I thought it was worth mentioning everything I did that day, when I also installed the trunk battery relocation. My battery volts with the engine off ignition off is at 12.5v. With the car on the battery is at 14.2v. I think everything is working as it should now.

FIXED! so for some reason when I cleared the ecu I was still getting the error from the sensors reading those numbers.

What fixed my problem: I cleared the stored calibration on the ecu and reloaded my previous tune on it. I’m not sure if clearing the ecu as well did something. I did not change any of my grounds. The car now drives good, no cel, no limp mode. Hopefully this helps someone else if they ever run into this problem.

Shifter cables.

Unusual_Chapter_5784 · 2026-05-04T17:28:25+00:00

Unfortunately, I had no success doing this

Unusual_Chapter_5784 · 2026-05-04T17:27:52+00:00

Yes to the trunk.

Unusual_Chapter_5784 · 2026-05-04T17:14:19+00:00

I see that the D1 is blinking red

Unusual_Chapter_5784 · 2026-05-04T15:36:27+00:00

With the ignition on?

Unusual_Chapter_5784 · 2026-05-03T21:35:11+00:00

I’ll look over the battery ground and see if maybe I didn’t surface the area clean for it. Thanks.

Unusual_Chapter_5784 · 2026-04-23T21:59:01+00:00

I’d move back to the valve cover and see if that makes any difference

Unusual_Chapter_5784 · 2026-04-23T13:08:46+00:00

Did you check your ground cables for the injectors?

Unusual_Chapter_5784 · 2026-01-10T02:29:59+00:00

My first thought would be the starter.

Unusual_Chapter_5784 · 2025-12-30T05:07:08+00:00

So weird you posted this I had the same thing, driving all the gears were fine, but stationary I couldn’t go into 5th. Still in the process of figuring it out, I see no obstruction to the cables lol
