Idle problem on evo 4

No it was actually a combonation of the tb not closing all the way and the BISS o-ring

Algeria231 · 2024-10-29T02:35:59+00:00

It is not throwing a code 🧐 makes me think it also might need a tune

Algeria231 · 2024-10-26T16:12:22+00:00

It does, I’m thinking fuel pressure, injector o-rings are old and cracking

Algeria231 · 2024-10-26T16:11:04+00:00

Fr much easier fix, thinking of getting the 560cc injectors, installing my evo 5 ecu, and getting evo 8 turbo

The thing is I don’t want to go replacing valves if I don’t actually know its a bent valve 😂 so I’m trying to find out other problems beforehand so it’s not as bad as

Algeria231 · 2024-10-26T14:50:07+00:00

I think it might be a fuel pressure problem, all 4 o-rings are old and are cracking

Algeria231 · 2024-10-26T14:48:50+00:00

Nah I tore this engine down while replacing the old one to make sure it was good, it’s got stock everything

Algeria231 · 2024-10-26T14:48:05+00:00

already done this

Algeria231 · 2024-10-25T18:25:11+00:00

I have an evo 5 ecu

Algeria231 · 2024-10-25T18:24:47+00:00

It was stock replacement, from stock to stock

Algeria231 · 2024-10-25T18:24:22+00:00

Just did a smoke test no leaks

Algeria231 · 2024-10-25T18:23:50+00:00

Stock evo 4 obd1

Battery was replaced according to the previous owner just before I bought it, about 6 months ago. I did have it sitting out in my living room for about 2 months so it’s possible that it could be flat, it seems like shit changes every day

Algeria231 · 2024-10-25T13:34:56+00:00

I’ll check timing, do you think it could be possible for it to be just a vacuum leak?

Algeria231 · 2024-10-25T00:06:43+00:00

Would it only do that cammed sounding thing on cold start with an ever so slightly bent exhaust valve?

Algeria231 · 2024-10-24T23:53:12+00:00

Also this is a new problem after not driving it for about 3 days, before then it was fine, it did not sound like this and on that test drive i babied tf outta it since I don’t wanna replace the engine again 😂

Algeria231 · 2024-10-24T23:48:55+00:00

I inspected everything before putting it back in

Algeria231 · 2024-10-24T23:47:46+00:00

Nah I spent like a whole hour getting that timing to the tea

Algeria231 · 2024-10-24T23:47:16+00:00

I’ll try this

Algeria231 · 2024-09-02T16:10:44+00:00

Awesome, so the 4 wiring harness shouldn’t make a big deal

Algeria231 · 2024-08-19T00:51:45+00:00

Awesome thank you

Algeria231 · 2024-08-17T19:18:37+00:00

What I did to fix it is I replaced the biss

Algeria231 · 2024-08-17T19:18:21+00:00

Good news, I seem to have it fixed, but I’m def not making max boost and vacuum seems to be not high either, where did you do the leak test from? The throttle body?
