intermitent problems
this seems to happen every 3-4 week where my 90 Buick Regal with stall with
any pressure on the gas peddle at first it will lose power but if i step on the gas and release it will be fine for up to a day. Twice it would die after warming up and sitting for a couple hour and then a short trip (2 miles) shutting off the engine and then starting it up within 45 min. Right now it's in my garage and will start, idle but if I touch the gas it dies. Replaced fuel pump, filter, MAP Sensor. Any thoughts? |

Look for a crack in the duct between the maf and throttle body if ok get it
scanned and look for proper air flow readings. check fuel pressure also.

Check the throttle position sensor...
