While driving my blazer started running really rough and back firing. I got it home. I was getting a cylinder 2 misfire code along with some exhaust codes. I took it to a shop for diagnosis and they said it was the fuel injectors. $1700 so I decided to do it my self. I noticed that the #1 injector clip by the #2 intake hole was missing. I believe that it is why I have the #2 misfire code. Will it burn out? Has it damaged the engine? Not sure what to do. Any info will help thanks.

changed ignition, fuse box

The biggest issue is when I put it in reverse. It bogs down, sputters and dies every time unless I give it a lot of gas. Buddies have told me it could be vacuum lines or a modulator valve. I had the vacuum lines checked by a mechanic and he said he fixed the problem. Can't find a modulator valve location or part for a 1998 S10 2.2 liter 4 cylinder. Don't even know if it has one. I replaced the spark plugs, sparkplug wires, alternator, starter, fuel filter and the fuel pump. These things helped get the truck started and running but the problem is still there. Any suggestions, input or help would be greatly appreciated!!

I have ordered the parts from GM

The lower dash panels are removed

I was told where it was but not how to reset it

the check engine lights comes on for a crankshaft sensor but ive already replaced it 3 times now with new ones in the past week and the same problem occurs. im driving for about 10 minutes and the engine shuts off on me. i cant figure out what to do

truck has run strong just this issue

Truck tries to go into 4WD while moving.

The shop said both sensors for the brakes work so it must be electrical. I took my truck to a dealer and they said it was an all around sensor, which the first shop said worked. They want $620. for the part. Does that sound right? Sounds way too expensive to me.

please explain or send a pic..thanks
