I think I lost an injector today

[93mustang2.3t]

I was driving back from autozone when I picked up my valve cover gasket and after getting up to 50mph rather quickly LOL the car started running really rough.

After I did my gasket I drove it again and it was still there so I pulled wires one at a time to see which wasn't firing and I noticed a diff when I pulled #2cyl and the motor died when I pulled #'s 3-4.

The only one it didn't make a difference was #1 cyl so I pulled all the plugs out regaped them and put them back in there was no change.

I then pulled #1 cyl wire again let it run for a min or two then turned the car off pulled the plug and there wasn't any gas on it so I then unplugged the injector and it didn't make a difference.

I'm getting compression in the cyl although I don't know how much. I am getting spark in each cyl even #1 so that isn't the problem.

What is your guy's opinion I think I fried an injector.

Another thing I have noticed is that I am running 12lbs of steady vac were I would ussually run 18lbs.

if its not running on all cylinders, then it won't make as much vacuum. you need a test light and test to make sure the injector is getting power

Ok I plan to check timing and check the under the valve cover tomorrow.

Swap the #1 injector into the number 4 hole and see if the misfire follows.

[93mustang2.3t]

I already swapped injectors did not change a thing.

you need to check your wiring also.

X2 on the wiring and on the vacuum hoses and pipe connections.

BTW, Felpro vc gaskets suck. You need a motorcraft one from ford for $30 and they are reusable for like 20 years. Anyway, you may have collapsed a lifter.

Well I'm going to check the injector wiring today the timing and look under the cover and see if there is anything wrong there.

[93mustang2.3t]

Ok well timings good injector is pulsing nothing wrong under valve cover visually but I can hear the compression escaping when I crank the car over I know it is from CYL 1 but from which valve I have no clue I'm guessing I have to pull the head off now?

[93mustang2.3t]

I think I'm just going to make a video of how it runs for you guys cause the more I listen to it the more I don't know.

[93mustang2.3t]

I can't take a sound video the camera broke.

[4bangstang]

Instead of pulling the head, leak test it!!!!! Man, I'm trying to save you from a headache and wasting time/money. You may as well just blow it up.

[93mustang2.3t]

I don't have a leak down tester and I don't have $85 to rent one plus I don't have an air compressor. There wasn't compression escaping through the valve it just seemed like it cause I had the intake off.
