87 chevy r20 code 44 please help

[cditeodoro]

Ok so my truck runs like craps as soon as it goes into closed loop. New motor New cts tps map tb gasket iac o2 fuelfilter and fuel pressure is 12 psi. I cleaned all grounds and reconnected them. After countless hrs researching I'm leaning towards the Bosch o2 I have is no good. Any help would be greatly appreciated. Oh no vac leaks either

[cditeodoro]

Oh yea the motor has an rv cam in it also, and I've swapped distributors with my brothers to see if that was the problem and still runs like crap. Also my 02 is not in manifold it's right below the flange in pipe because the manifolds are off newer style truck.

I don't really have access to a scan tool. Could u use a meter to test it or no.

Try an NTK o2. I have the same truck, had to change it and was warned to stay away from bosh o2 s as they give problems.

I'll get a new 0 2 today and see what happens. Will post results thanks

Ok put a new ntk o2 sensor in and replaced egr valve gasket. Truck still runs bad.  I noticed when I pulled the vac line on the driver side of tbi ( which is hooked to egr solenoid) some fuel leaked out! What is going on here? I'm at the point of selling this thing after putting new motor if I can't figure it out

Where are you located? 

You can make a scan tool or even buy a cheap one for OBDI and unless you are going to junk it, it's a worthwile investment. So if you remove the EGR sol vacuum hose fuel comes out of the port? How much fuel are we talking here?

[cditeodoro]

It doesn't pour out but it's wet and is def fuel. I don't know why fuel would be coming out of It. Just so we're clear it's coming out of tbi port not solenoid end. I'm loosing my mind

Located in Delaware.

Can you post a vid of it?

[cditeodoro]

You want a video of truck running or just the leaking ? I will post first thing in the am. Hopefully we can get this thingfigured out . Possibly tbi rebuild?

[Irish_Alley]

what part of delaware im in Harrington. but think vile wants to see how much fuel

[cditeodoro]

Ok I did a video but it's not loading for some reason. I live in Newark it's about a hr and change from Harrington. Didn't notice any fuel out of port this morning. It runs great when first started and then as soon as it goes to closed loop? The idle goes all to heck and you have to feather the gas to drive while it's stumbling and sometimes backfire through tbi.

If the c\e light is on the auto parts should have a key to plug into the aldl terminal a to b,or just make a jumper then read out flash code.44 is a lean code
