Tried swap with good injectors which is Fote-D5A it doesn't ever work it shake worse than it is.

Original fuel injector is Fote-D5B but they are 19 lb injectors.

They look ok to me but body of black metal round is rusty between orange plastic coil sit on it.

I decided left fuel pressure there it was sit at 38-39 psi 2 hours later I go check it was 34 psi.

 

Ok , you have a fuel pressure gauge . Get a plug that fits the injector plug and do a basic flow test . Pressurize the fuel system . write down pressure . Energise one injector for 1-2 seconds . no longer . Write down pressure . Pressurize fuel system again .Go to the next cyl. Do that on all cyl. to ck for equal injector flow . any that show a low pressure drop have a problem .

 

Yes I have fuel pressure gauge that go on Fuel railing. Fuel injector plug from junkyard wiring to battery to energize injectors?

My question if 1 bad injector wasn't flow fuel well that mean pressure on gauge not drop?

 

Correct . Wire junk yard plug to injector . One side power + other side negative - . If the injector does not flow , there will be no pressure drop . The pressure drops should match . If one drops more or less pressure than the others , it has a problem . No drop in pressure = no flow . Too high a drop = too much flow . I would put a fuse in my jumper wire , and do not energise ( jump ) injector for more than 2 seconds .

 

Forget to get a fuel injector's plug from the junkyard. I found something interest.

I unplug vac line to EGR valve and put bolt in vac. Drove 30 miles no engine light ever come ON.

I doubt bad egr valve but mileage 16 average.

 

If a miss is present , EGR monitor and action may be suspended .
