any chance you guys could give me some possible issues to check/look for on a car that stumbles/falters under acceleration when hot.

thanks

1st: Is this for the bonnie? If so I'll move it down to the 92-99 forum

2nd: Hot as in how? Hot weather or hot engine?

I thought fuel preasure was not dependent on temperature. So that would mean it isn't the fuel pump.

plugs and wires are not the newest I dont think. I will have to find that out.

When catalytic converters heat up (old cats), the internals swell, closing off the flow. The Cat is a strong possibility.
