Engine Scan showed nothing. Never consistent when it does this, sometimes fine and other times Check Engine Light flashing when accelerating or going uphill. Spits and sputters going uphill and no power sometimes when I accelerate. Now the darn thing just won't start. Sound like she's getting too much gas or none at all.
Check Engine Light flashing when accelerating ,severe engine misfire . Something in the ignition system is breaking down under a load . If the starter engages an spins the engine when you turn the key to start an it doesn't start an run , it has no spark or fuel pressure . If you don't know this or how to diagnose .suggest you take your vehicle to a qualified repair shop . Pull two plug wires off the top of the same coil an crank the engine , if you do not see a spark jump from one coil tower to the other you have an ignition system problem . ignition module or crankshaft position sensor

SOURCE: Engine running really rough...whine sound when it isn't.
The run rough problem is due a cyl.mis firing,it becaused buy a bad plug,plug wire,coil,or even the ing.module. the servive eng.light flashing is warning you that you have a cyl.misfire that can cause damaget to your catltic converter if you continue to drive it.with may lead to why you think you have a exhaust problem,it may be colgged.
SOURCE: I have pontiac sunfire 96 model 2.2L engine. At
check to see if valve cover gasket is leaking oil onto spark plugs...causing a misfire; if so replace valve cover gasket; spark plugs and spark plug wires.
SOURCE: poor acceleration while trying to pass and check engine light on
You said it struggles between 2500 and 3000 RPM. checking the hose for vaccuum at idle won't work. Rev the engine to the problem RPMs and check. That will tell you about vaccuum. As for where it goes, it won't go in the same palce as the brake booster. There will be another connector. If the re is a T there now, it sounds like someone else may have changed things around.
SOURCE: Describe your service engine soon light blinking
you have a missfire that is why the light blinks, it also will have a trouble code stored showing which cylinder is causing the problem, but this sounds like a plug or plug wire issue.
