He bought it brand new when my dad bought his 79 short bed. They both got the first sr5s in the Chicago region

 

Arcing coil pack/wire


Or bad gas

 

None on the phone, it’s been a few years since I’ve seen it. Last I talked to him he was thinking 15k.

 

You can feel it all the way through yes

 

Yeah that's true too on the gas.
And his sits for a up to a week at a time regularly, so definitely could be in engine side fuel system

 

@eon_blue iys pretty much this, but clean

 

Yes I usually don’t drive it but crank and let it run daily

 

Can you swap the coil pack positions? Which ignition do you have on that thing? 4 individual coil packs, one on each spark plug?

 

98 I believe is 2 coils and 2 wires. I would be suspect of the wires

 

Oh well that's good to clarify that. Scratch the sitting a week at a time. Sitting isn't bad. I was just saying so we can see the whole picture. Something will come to our noggins

 

Mine has 2 coil packs and they do 2 plugs each

 

You got a scanner that can log what cylinders are misfiring?

 

I plugged my dads snap-on scanner in it and under data display it shows each cylinder and shows if it’s misfiring or not. It lays out like this:
Cylinder 1 Misfire.............0
And so on for each cylinder

 

That works. So it’s showing none misfiring?

 

Correct, it's showing no misfires

 

None...nada.... my dad just told me he has a set of noid lights to check injectors with. Maybe gonna try that. Edit well not maybe but I’m gonna test that

 

Can you graph your front air fuel sensor, is the graph really “Dirty” aka lots of ups and downs, working properly at idle it should look like a sinewave. If it’s all over the place, exhaust leak

 

His scanner doesn’t show graphs that I’m aware of.

 

Oh. What model

 

If it ends up being a bad injector? Which ones should I replace them with?????
