If it was in a wreck, chances are the heads will be fine.

Good word, it is a chance. You aren't willing to chance a CPI unit which is much simpler bolt on device, but you're willing to chance heads?

They have their places, but in this case, this is not something I would do. But that is my opinion.

comparing a factory flawed CPI injector swap to a good head from a body wrecked low mileage 1995 engine is ridiculous and you are now nit-picking my answering in other threads to back your point?

Comon now.......

I'm not nitpicking. You acknowledge it is a chance, yet you are against it for something much more simpler, less time involved, and reveling.

Have you done any deep work like that?

Sure, you should/could have the heads checked.

Low mileage does not always or automatically mean good. That would be an assumption.

It is an option, I am not arguing that the valve seal swap is a bad idea, I am giving the guy other options to look into.

So please understand that.

i just noticed this today. when accelerating the RPMs twitch. like 300 at a time. they go up and down like 150 each way. while misfiring that is.

it is almost like the gas is pulsating. like it sends gas in then cuts off for a split second, then gives gas again. it isnt getting any better with a new tank of gas from a different gas station. whats next for me to do?

Have you pulled your plenum to check for washing? Again, one of your poppets may be stuck open. Your fuel pulsator may also be going out. Have you run a pressure test at the shrader valve?

where is the shrader valve? 95 W 4X4 4.3

Back of the plenum on the inbound fuel line, looks like a fat tire valve (may have a black plastic cap on it)
