THIS JUST HAPPENED TO MY 5.4. HAD IT PUT ON COMPUTER TO FIND OUT WHICH CYL'S WAS MISFIRING, AND REPLACED THE COIL PACKS ON THOSE CYL'S. THIS FIXED MY PROBLEM. IT WAS AN EASY FIX BUT EACH COIL PACK IS AROUND 50$, AND EACH CYL. HAS ITS OWN SO THERE IS 8 ON OUR ENGINE NOT A CHEAP FIX. NOT GOOD TO TRY TO DRIVE WHEN ENGINE LIGHT IS FLASHING WAS TOLD THIS CAN CAUSE CATASTROPHIC DAMAGE TO THE ENGINE. HOPE THIS HELPS, AND GOOD LUCK.

2002 Chevrolet Blazer won't accelerate past 30mph


A flashing check engine light means the engine is misfiring. This flashing light will eventually set a code in the low 300's. When you get the code it will tell you which cylinder. If you get a straight 300 it means multiple misfires. Right now if the light is only flashing, check the secondary ignition for loss of integrity. It's more than likely there. I hope this helps.

2005 online 5 cyl has no power 40-45 is as fast as it will run just Boggs down as I try to speed up


assuming no misfires(flashing check engine light) first check fuel pressure. if ok, does this problem get worse as engine warms up? sounds alot like a plugged catalytic converter. have it checked professionally. if so, find out why ie. misfiring, oil consumption etc. they usually don't plug for no reason. many people have them replaced, and it happens again. have a reputable shop perform engin enalysis to find out why. good luck!

Sounds like it may be running a bit lean - do basic checks for air leaks in the induction system (such as leaking manifold gasket, loose hose fittings to air flow sensor etc).
Condition of HT leads also worth a check.

Engine light flashing


It sounds like you have a misfire. Anytime a misfire is detected by the powertrain control module (PCM) it flashes the check engine light (CEL) on and off. Do not drive it this way because it won't take long to damage the catalytic converter. Have the diagnostic trouble code (DTC) read with a scan tool or "code reader" to see what DTC or DTCs are set. If it's a 4 cylinder, it will have a P0301 set for a cylinder # 1 misfire, a P0302 for a cyl # 2 misfire & so on. If the misfire is random (ocurring in multiple cylinders intermittently) it will have a P0300 set. Once you know which cylinder is misfiring you can check that cyl to see what the cause might be. It could be an ignition coil or spark plug failure. The # 1 cyl is always the one closest to the front of the eng or this car, the one closest to the passenger side fender.
