HOW DO TEST TO MAKE SURE THE ENGINE IS FIREING ON ALL 8 CYL'S
I HAVE A 95 5.0

CC'S95GT · Dec 12, 2014

A laser thermometer aimed at each exhaust port. (no fire no heat)
To ck spark coming out of the dizzy, just put the timing light on each spark plug wire.
Noid tester on each injector will tell you if the signal is getting there to fire the injector but not if the injector is actually working.

What's your real problem?
A moderator will probably move this to the 5.0 section when he gets up.

Yeah, what's the actual problem. I think you should be able to tell if its firing incorrectly....

Also, WHY ARE YOU YELLING!

You could run a KOER cylinder balance test.

What is a KOER cylinder balance test ???
it runs fine one day and the next It feels like no power then the next day the power is
i'm a old school hot rodding back from the 70's. I would start at checking the spark at each cyl to make sure it's there then go from their.
I have new plugs,wires,msd coil. msd6al-2 box and it seams like it should have more power then what it dose

Take that msd coil off, put the stock one back on. Bet that helps a bit.

the5.ohh · Dec 12, 2014

Serious question aswell, what did you gap the plugs at? Which plugs did you put in, which plug wires?

a Haynes/Chilton manual will explain what KOEO and KOER is well and how to read codes with a paperclip.
what mods do you have on the engine and what plugs are in it too. 5.0 don't typically like platinum plugs.

why do you say that I have used their coil in a couple of other cars and it felt like it did more good then harm ....

Ignore him. MSD coils are fine, until they start buzzing.

Jump the 2 wires in the engine bay with a paper clip for the engine diagnostics... turn car on. After codes stop flashing floor the gas briefly then it will start its compression test. Should take about 5 minutes.

And then how will he know if a cylinder is not 100%?

OP: Just buy a $20 code reader and be done with it. It's easier than counting check engine light flashes.

Well, for one, the code reader won't do a cylinder balance test... which is what he was instructing on how to perform.

And the cylinder balance test will tell you if a specific cylinder is not contributing properly.

But you would have known that if you had looked at my posts.

Really? That's funny because I did one with my code reader. Innova 3145. If you think I'm full of shit I'll even make you a video. You have a lot of nerve chief. I know what a cylinder balance test is lol. In seas of counting flashes just write down the codes and check the book after....

Sighhhh, buddy if the guy doesn't know how to read the flashes it will just confuse him this is what I'm trying to say. The code reader really makes it easy. Obviously it's a glorified paperclip but if one of the cylinders is off its easier to see what codes on the reader come out then counting the flashes. Of course you have to give it a shot on the throttle to start the test te reader can't start it on its own.

Equus 3145 scanner can do a cylinder balance test on any obd1 ford sequential fuel injection engine, here is a video showing how to do it , basically you just blip the throttle after running engine running codes and it will take off on its own , code 90 means all pass , if say cylinder 3 is down on power output you will get a code 30 , or cylinder 4 will show 40 and so on
