    Good Luck on getting your refund and thanks for the info. I will check my fuel supply from the pump. I am also going to do some work on the pollution control system. If anyone has any ideas on that let me know.

I have a 1997 SAAB 2.0 Turbo and it has started to run rough after it warms up and when driving it loses power and runs very rough until power taken off. Any ideas?

suspect low fuel pressure to the injectors
run the fault codes to determine where the fault may be before you spend money

A couple of possible problems, low compression on one or more cylinders, possibly a burned valve, possible headgasket leaks, have the compression tested and checked for a headgasket leak, both of these conditions would cause a rough idle and then seem to run normally when warmed up.

93 chevy lumina runs rough dies and won't start after it warms up

Back firing is usually an indication of a timing issue

The timing chain is most likely worn & jumped a couple

Have a '94 S-10 Blazer Tahoe 4X4 and it starts

My suspicion is a starter going bad. Sometimes when starters get old and worn they will start good when the engine is cold but not when the engine is warmed up. Did you perhaps notice that lately is seemed to drag when you tried starting, especially warm or it seemed to crank a little slower? I'd replace the starter. Hope this helps.

CHECK THE FUSIBLE LINK THAT COMES OFF THE STARTER POST.THEY LOOK JUST LIKE A WIRE, BUT THEY GET STRECHY WHEN THERE'RE BLOWN.IF THIS IS THE CASE YOU WILL NEED TO FIND THE CIRCUT THAT CAUSED IT TO BLOW,AND REPLACE THE LINK.
