Not necessarily, could still be missing for other reasons.

 

I think its dry idk the one where you take out the injector and put in the hose and crank the engine a couple times

 

Compression test is done by removing spark plug and connecting...not the injector.

Check for injector pulse. No pulse, it will not open.

 

Sorry thats what i meant the spark plug not the injector lol. but ill check for pulse when I get back to my job Tuesday, just hope someone has a noid light

 

You can back probe the injector plug with a DVM also.

 

What is a DVM?

 

Digital volt meter.

 

Okay guys ive done every test possible injectors are fine, plugs, wires, cap, rotor, connections are good, compression. But still shows a misfire on the computer... no code tho. I give up! I think its just a pcm issue? idk but im done monkeying with it she drives beautiful and just took it off roading the other day with no issues

 

Just keep using the Techron for now.

 

Okay guys found the issue, driving down the road and the welded seal around the catalytic converter came apart and started leaking like crazy. Truck started to run and drive like crap I had to baby it home. So do I have to have it welded in or can I use clamps? Thanks for all the help too btw. Love these forums!
