new problem

[stoneymonk]

I have a 1995 lumina ls 3.4dohc engine.When after i drive it for about 70kilometers or 30 miles and shut it off,then restart it,it seems like its choking for gas and boggin out for about 1 minute then runs fine,have cleaned the mass sensor with sensor cleanor and hve done minor tune up of plugs pvc and air filter.Goin to change out the fuel filter thinking it clogged but whe running its got a lots of power.Any other ideas.Thaks and sorry bout the long post.

does it only do it when the engine is warm? or does it do it when its cold (1st start up in the morning)? Definatly replace fuel filter... might not be a bad idea to put a Fuel pressure gauge on it to see if maybe the pump loses pressure when warm?

Does it sit for any ammount of time before restarting it or is it literally shut off...... then start again? maybe something to do with EGR or IAC... have you pulled the iac and cleaned it? unhooking the EGR and see if it goes away or happens more often or nothing changes...?
