i have an early 99 f250 6 speed i have a pretty steady skip i used a temp gun i found i have both 2 front cylinders on the passanger bank that are cold i bought it like this, now im thinking uvch so i got one, my question is is there anyway to check the injectors while i have it apart?

i also get no codes

 

In a round about way...

Put the new uvch on... Start the truck with the valve covers off... The injectors should be spilling oil out the little spouts that come off the solenoid...

 

ok i did uvch not the issue got 2 injectors, now my issue is how do i get all the oil and fuel out of the cylinder

 

Install the injectors, making sure to lube them liberally first... Do not hook up the electrical for them. Torque them in place... Pull those glow plugs for those cylinders and spin the motor over... Make sure to have your valve covers back in place with a two bolts, top and bottom to stop the fluids from hitting your shop wall.. Then put the glow plugs back in, connect everything, put vc's back on and start cranking on her...

 

i did 2 injectors i got used from running truck, also did uvch and glow plug relay all from a running truck now its skipping less before was 5 or 6 cylinders now its 7 much much better but not perfect, hoping i can get injectors buzzed while i can get used parts cheap
