Problem with EJ22T engine (idles but does not rev up)

[s'ko]

So first I had a crack in my cooling system that I decided to fix other day.

I took the intake manifold off and took some JB Weld to the crack and sealed it.

While waiting for the JB Weld to dry, I decided to clean up the engine bay of it’s rat’s nest. I taped up the wires and zip tied them out of the way.

I reassemble the engine and start it up and it runs idles but does not accelerate.

Basically the engine will idle OK. It’s not smooth but it will do it with a slight hiccup.

Then when I give it gas, it will not accelerate at all, it just idles as before. This coil pack will click faster and when I removed a plugwire to see the spark it did increase in speed. After I let up on the gas, it will sometimes surge a little and there will be this knocking noise coming from inside the engine.

I am not getting any engine error signals.

I have removed the intake 3 times already to make sure that I didn’t miss anything and it still does it. There is no unmetered air coming into the system.

Looking at the combustion triangle and I know I have compression, spark looks like it’s there and same with fuel. I am guessing that there might not be enough fuel.

Just to verify the three fuel hoses, the one from the filter goes into the top hose. The line at the bottom to the rear of the engine goes to the hose right next to the fuel filter and the line at the bottom to the front goes to the evap canister. I will test my theory by spraying some starter fluid into the intake while the engine is running and see if it will accelerate.

What could cause a fuel starvation issue like this? Pressure regulator?

Thanks

Running OK before the cooling sys. repair?

 

Should rev in neutral even w/poor fuel delivery.

 

Only one I had that wouldn`t rev in neutral had a badly plugged cat.

Try a vacuum gauge.

 

Sounds like plug wires incorrectly positioned.

It ran fine before the repair.

 

The car is in neutral when being revved.

 

Checked and tripled check the wires.

 

THanks for the reply.

 

I am at work right now and will not be able to do any tinkering until tonight or tomorrow.:-\

You didn't drop a wrench or bolt down into the turbo did you? How about tape or a rag in the throttle body or intake tube?

Big clues.

made corrections to the original post.

 

The spark increased in time with the clicking, but the engine does not rev faster
