A few weeks ago I was driving and it started running and had no power. After a minute or two it started running normal. I started it this morning and when I started the engine it started running rough with no power and blowing smoke. When I let off accelerator it dies. It will start back but won't idle. I can hold accelerator and it will run rough and blow blue smoke but it has no power.
Any suggestions on what to check?
Wayne , check for EFI codes first......then fuel pressure............Then check wire harness at the TBap sensor/TPS and CPS. If the TBAP sensor harness has never been changed, it is bad

Check the throttle body adapter for cracking right above the flange that bolts to the head.
Check the oil level in the crankcase to make sure it is not over full with gas/condensation causing dry sumping. (blue smoke )
I would check both base and airflow voltage on the TPS after completing the above........
