I broke my car... Now with codes!

[Devin]

Can misrouted hoses to the tb or iac cause the car to run like crap?

There are two little hoses that go to the tb and two that run to the iac. I don't know if I hooked them up right. At idle the exhaust sounds staccato (putt putt putt) and there is very little power. I took the intake off again, checked the plug wires and the gaskets and torqued the intake down properly, and now it still sounds like ****.

 

[SHO_91]

Mine was like that when the hose to the brake booster got disconnected (back of the intake). But it ran crappy only at idle (aside from having almost no brakes).

 

[SuperHO]

secondaries workin? also make sure the manifold to head gaskets are flat.

Those are coolant lines, so probably not. The one underneath the TB that goes between the heads would affect idle.

What work did you do? If you pulled the plug wires, you probably have a problem there.

 

[SuperHO]

the hose going to the bottom of the throttle body is PCV, and as long as the port on the throttle body's blocked off, it won't affect nothin. is your firing order correct via SHOforum? remember, AFAIK, there has yet to be a shop manual released with the proper firing order in it.

 

[Devin]

I double checked it with the sticky, and I've done it twice already, so I'm pretty sure it is accurate. Secondaries are working. I unplugged the canister while it was on and they both actuated. PCV hose has been replaced previously and I believe it is hooked up properly.

The first time I had the problem I got ****** off and threw a handful of water on the (not hot) intake and it stumbled, so that made me thing it was an intake leak. I took the intake back off, cleaned off my gaskets (they have ~10,000 miles on them), noticed that they were in good condition and re-torqued the intake to 20ft lbs. I made sure the ground strap was connected properly to the intake.

Is there a way to find out if all of the cylinders are firing?

My friend suggested that I take a propane tank, put a hose on it, crack it open a bit and run some gas around the edges of the intake, and if the engine picks up RPM then there is a intake leak somewhere. Does that sound about right?

Oh, and lastly, when I unplugged the IAC the engine died, which I thought was wierd. I just figured it'd screw up the idle.

Cylinder balance test.

I've heard of people using starter fluid to do that, but I've never done it.

Sounds about right. The engine couldn't get any air.

I think your problem is ignition or injector related.

 

[Devin]

I did have to tug on the injector harness a bit because it didn't seem to want to be long enough when running it under the coolant manifold. I guess it could have either screwed up a wire or tugged one of the connectors clear.

When priming the fuel pump, does it blow the fuel into the cylinder? Meaning if I were to prime the system a couple of times, and then remove the plugs, would the cylinders be wet?

 

[Eric VerValin]

Nope... it just builds pressure in the rails, and in the lines leading up to it.

And... starter fluid works great.... works even better once the engine is warm and quiets down a little.

Codes

KOEO
111
KOER
26
18
25

Balance test:
Cylinder 3
Cylinder 6

What the **** did I do!?

 

[St Louis SHO]

Crossed 3 and 6? lol or did the coil die on those 2 cylinders?

 

[Devin]

That could be fuel too, right?

edit: ******** cracks me up!

 

[SuperHO]

i'm not too familiar with 2 digit codes, but if 3 and 6 are gettin funky, i'd start looking at the coil pack since they're on a shared circuit. also, push down on the plugs for the injectors for those two cylinders to make sure they're plugged all the way in.

 

[K-Dawg]

I don't think so.

 

[jonheese]

I don't think so.

K-Dawg is right.
Cyls 1 & 5 use the same coil, cyls 2 & 6 use the same coil, and cyls 3 & 4 use the same coil.

Nothing in common between 3 & 6 in the coil.

[Devin]

That's why I'm wondering if I screwed up the harness. The SPOUT code is wierd though. No reason why that should be in there. How do clear the KOER codes?

 

[jonheese]

Code 26 means the MAF sensor voltage is out of range. Clean it with some electrical contact cleaner and wiggle/check the electrical connection.

Code 25 means means no detonation was detected by the knock sensor when the engine was goosed during the KOER test (did you goose it?). If compression is down on multiple cylinders (as may be indicated by your cyl balance test results), that can cause the engine not to detonate and thus trigger this code.

Code 18 means the SPOUT signal is lost. Check the SPOUT connector and make sure it's plugged in, as leaving it unplugged with trigger this code. Otherwise, it could be caused by a break in the SPOUT wire, a bad DIS, or a bad ECU, in roughly that order of likelihood. Does the tach work okay?

I can give you more in-depth troubleshooting procedures for these codes from "How to Tune and Modify Ford Fuel Injection" by Ben Watson, if you need them. I just have to retype the info, let me know.

Not yet. I want to check the wire harness and stuff first. I'll post again after I check everything up there thoroughly.

Okay, fine by me.

I usually prefer to pinpoint my troubleshooting to be more efficient, but if you really think there's a problem in the harness you will be able to find quickly, by all means, good luck.

I just wanted to save you the trouble of writing stuff up, but if you think it'll help, go for it!

This irritates me to no end. It was working fine before I took it apart, now everything is breaking! And it's too cold and wet to do anything about it so I'm stuck driving the Impala.
