Cylinder 2 misfire

New Fuel spider ran fine last night now cylinder 2 misfire. Could this be from the injector not being in right. Don't smell fuel just getting cylinder misfire. Plugs, wires, coil, dist cap and rotor all replaced in September.

Ok #2 cylinder wire was loose on Dist cap. So that's done. Now still running like crap. Replaced intake gasket and new oring on the fuel meter. No other gaskets, that I could see. Do I have an air leak?

are you sure you got the nozzles in the right hole. what cap and rotor you got on now.

 

[insadj05]

Yeah, after I put nozzle 4 in to 2 and pulled it out rechecked the others and all were good. I double checked as I can see that side from the butterfly on top of the intake. I was out of town when I had to replace the cap and rotor and had to get em at Advanced Auto. Don't recall the brand.

i would pull the cap and inspect it next.

Ok will do. My son also thinks maybe the oring around the metering valve on top my have rolled out as tight as it is or something to cause vacuum leak. I won't be able to look at it for a week. When I put the intake back on it seemed high centered on that fuel metering piece. It wasn't a great amount but it was some. So I started from the center out and tightened the studs a little at a time. I'm wondering if those may have caused a vacuum leak or even caused to move that oring some.

oring should not roll off but if the fuel body harness is not positively latched completely some connections may not have made contact.

hardware holding fuel line bracket in back of engine. and the little bracket holding the front part to the fuel body. one other thing if this isd the original injector installed at the factory. replace the whole unit with the redesigned unit which includes the fpr. http://www.amazon.com/Delphi-FJ10566-Fuel-Injector/dp/B000TYLIFS

also when removing the plenum the oval oring around the fuel body to seal the against the plenum might make it sticky to get the plenum off if ALL the hardware is off.

Is it easy to to replace? And when should I do it? (Replacing this part)

Been gone for over a week. Havent had time to look at it at all. It's going to be 3 degrees for a high then next two days. No heater in the garage and really don't want a fire heater when dealing with fuel. Maybe over the weekend. Will check cap and rotor and connections. Not getting any codes though which really seems strange.
