Not able to accelerate after about 25 to 30

Would it be worth the time to go out and re do the injectors again? I'd rather it be proper than close to proper

An ignition coil is an ignition coil, so the number of cylinders doesn't matter, 4, 6, 8, 10 would all use the same coil and produce "enough" spark

You could have a "bad" coil, you can't really test them, well you can test if they are "real bad" but can NOT test if they are good

So if you think its a spark issue then swap coils

In an 8cyl engine the Coil sparks 4 times per 1 revolution of the crank
So at 800RPMs the coil is sparking 3,200 times PER MINUTE
At 3,000rpm the coil is sparking 12,000 times per minute, that's 200 TIMES A SECOND

A failing coil can have a "delayed" recovery, causing misfires at higher RPMs
Coil needs time to "recharge" between sparks, doesn't need much but needs some
So its certainly possible for a failing coil to cause your issue

You said that the injectors layout followed the firing order, should the wiring match the firing order instead of what was recommended as well? An I never found if a motor being a high out put was specific to sequential fuel injection or if it could be a ho batch fire

 

[RonD]

Wiring would be what the computer uses and then changed to match HO firing order if it was different

So you need to know what V8 engine the computer was build for

When I search the number on the pcm I found it went to a 88 to 94 or 93 f150 302 v8

 

[RonD]

Did any have HO engine?

I don't quite remember but Ill try too look it up tomorrow when I have daylight to see the numbers, I went out to see if I was losing spark anywhere and I had noticed that lil bits of spark were coming through my line going from my ignition coil to my distributor, they were all along the line touch the plastic that was under it, I swapped my line and it feels kinda better, I'm checking to see if my injectors are working like they should be

 

[RonD]

You can get a NOID light and timing light and check if the injector is opening just before spark happens on that cylinder, would appear almost instantaneous

Idk if it's workin at all I can't feel the pulse that I can feel on others

My rear driver's side injector doesn't feel like it's pulsing, when I rotate the injector slightly so it's not putting tension on the wire, the motor seems to cut out real bad like it had been doing when I get going down the road, all the others on my driver's side can be felt pulsing when the engine is running

 

[BIG_RanGer1121]

My pcm when I look up the part number is telling me it's for a 92 or 93 f150 or bronco with a 5.0 in it

 

[BIG_RanGer1121]

The last letters of it are, aha I mean it's capital but does It mean that it's a vin h?

After relocating some wires on the injector line, it didn't want to start even though I was getting voltage to my coil so I swapped my coil an it start but sounded bad like something wasn't working properly, I kept messing with stuff and found that some of my spark plug wires were backwards when I was trying it before, a sound seems to be coming from the passenger side what seems like the oil pan but Im pretty sure it's not rod knock, my roommate said it sounds like I don't have any oil in it, I know Ive got oil in it , but Ill add more since none is on my dipstick, the repair manual I have says that the 92 - 93 ford pcm for f150s was batch fire so I wired it out like that on the injector wires

 

[Dirtman]

my roommate said it sounds like I don't have any oil in it, I know Ive got oil in it , but Ill add more since none is on my dipstick

Uhhh dipsticks don't usually lie...

 

[BIG_RanGer1121]

after yesterdays rewiring, it now seems like I've got some kind of a knock coming from the engine now,not sure what it is figured it might something not working but it seems to follow the crank so I think this engine might dying currently, time to get another I suppose,

Yea last night after I was showing my buddy what sounded wrong, I went to check the stick and nothing was coming out, he said my oil might be pooling up on my pistons but, I checked the oil again today and it had oil in it, the motor sounds like its out of time or something, I can't rotate the dizzy without the engine just bogging and dying, the idle has becoming disturbingly low as well since rewiring, I took the number one plug out an it's covered in carbon buildup an was wet still from what seems like oil
