stumbling
I have a 90 331 stroker. It has been doing great but about a week ago you would be driving and it would start stumbling like it is running out of gas, and a little popping and backfiring.
So I replaced the fuel filter-no change the I replaced the fuel pump-no change then I replaced the ignition modual-no change I am running out of options. I have 40lb of fuel pressure with the vacume line off the regulator at idle. This is a inerment problem it does not always run like this,but here is whats weird you can cycle the key off and back on quick asnd the stumbling goes away |
