Start by checking each cylinder for spark with a good spark tester. A misifre is either spark or fuel, so you can cut the problem in half. The engine light is probably on due to the misfire.

2000 GMC Sierra w/4.3 misfire on #2,4 cylinders


If it were low fuel pressure misfire , it wouldn't be cylinder specific misfire #2 , 4 it would be P0300 random misfire . I would think fuel injector's too . When hot they could be breaking down electrically , more resistance . If they tested electrically with a lab scope they would know for sure . Misfire from sticking fuel injector no fuel misfire

HEVROLET BLAZER 2000 MISFIRING


Timing is off,problem with timing chain,also check fluids in ******,plus also if you have a distributer in your vehicle,if it is cracked,moisture getting in and ruining the points,-that is if your vehicle has a distributer! This will make a vehicle run rough as well.
You can have new plugs put in,but if your spark plug wires are cracked or worn,this will also creat misfire and backfiring.

No, the catalytic convertor does NOT sound right.
Normally with a random misfire a tune up takes care of it. What has also caused a misfire on those early motors is the popet injectors. They were prone to having problems and have been updated back around 2000 or so. But usually its a cyclinder or two or three or... misfire. All popets going bad is unlikely.
Might try changing the fuel filter and maybe checking pressure. Just the key on pressure should be 60-66psi. While running it may be around 60 and a snap of the throttle will make it rise to 65 or so.

I have a 2000 Chevy Blazer. It was tuned up about 1 month ago trying to solve a problem with quick exceleration (it wouldn't). Tune up didn't fix it and the garage cannot figure out why it's doing it....


sounds like plug up injector try cleaning injector not by put in injector cleaner in the tank ,if that doesn't solve your problem, you probably need to replace your injector whit the new in prove ones.cosidering that someone check pressure and they found at least 62 psi
