X-No-archive: yes

FatHog - I run mine on Regular Unleaded but it does like a tank of Premium Unleaded about every 3rd or 4th tank.

My cad just stopped the other day while I was pulling out of a parking lot. Two sets of auto-mechanics proceeded to rip me off and the car is still not fixed.

I'll try and post it as a new thread in a bit - but for now - anyone have any suggestions? The ignition module or the fuel pump maybe?

Thanks
