It idles and runs smooth and normal. It won't go higher than roughly 2 grand on the tach. Everything else is fine, itl go faster if down hill but uphill bogs down to about 10 mph, with a steady flat road speed of about 30 tops. As I press the gas pedal its normal response curve up to about 20% and then nothing. I have no clue what's up. I'll get a code checker tommorow and see if any new codes are displayed. 185k miles on it BTW.
