Rev Limiter on ZF5?

Hate to suggest the parts cannon approach, might be more cost effective to pick a bunch of spare parts from the junkyard and swap them out one by one. I just feel like if your tach signal just totally goes dead and the truck dies and you've also got these other seemingly related issues, there is at least something going on in the coil wiring or the coil itself.... or the distributor... or the ignition module.

I'm not sure how 92 factory tachs are set up but on first gen trucks they are only accurate for V6 engines unless you add a tach signal converter box for 4 or 8 cylinders... I never did that with mine and it's nowhere near accurate. 3-4000 actual RPM will top out the gauge.

Yeah im gonna grab a new coil and see if that helps.Thanks for the info on the tach, ill look into a converter or just a mechanical tach.

I used the A9L ECU with my swap for a while---I'm pretty sue the A9M is for the AOD transmission. I also use GT40P heads and thought my stumbling problem at higher RPM was the valve springs. I put Alex valve springs in it and it made almost no difference. Now that Ii have the Megasquirt PNP ECU in it I still get a little stumble on moderate acceleration through 3500 RPM. Probably a fuel supply problem or ? Under full throttle I don't have any issues.
