Next time I tried check engine light came on which means it threw a code. I will check out that code tomorrow. Making progress. I least I know it WILL make full power. Also I need to diagnose the non working cruise control.
On the cruise control front there's some good threads on the troubleshooting. Mine was a hole had worn in the vacuum line running to the cruise diaphragm on the drivers side. There's also a vacuum line that runs to a clutch pedal switch too.
