I did a tune up to my blazer. i changed the spark plugs, wires, distributer cap, and changed the oil. it was running fine before the tuneup. now i have a miss fire and the truck runs rough. i had the spark plugs and the wires checked. what else could be the problem?
Recheck the Firing order. 1-6-5-4-3-2 On the distributor cap passenger side radiator to fire wall. 2-4-6-coil On the distributor cap drivers side radiator to fire wall. 3-1-5 Cylinder passenger side radiator to fire wall 2-4-6 Cylinder drivers side radiator to fire wall 1-3-5 Good luck and this should help and check to make sure the cap is on right.Recheck the Firing order. 1-6-5-4-3-2 On the distributor cap passenger side radiator to fire wall. 2-4-6-coil On the distributor cap drivers side radiator to fire wall. 3-1-5 Cylinder passenger side radiator to fire wall 2-4-6 Cylinder drivers side radiator to fire wall 1-3-5 Good luck and this should help and check to make sure the cap is on right.

Make sure the plug wires are in the right place. The passenger side is cyls, 2 4 6 and the drivers side is 1 3 5. The dist cap should be marked but the pass side is, going front to back 2 4 6 , coil wire and the drivers side is 3 1 5

if you checked the plug gap before install then its has nothing to do with them. changing the wires you may have some wires in the wrong place in the distributer cap. check the firing order to make sure the wires are in the correct place both at the plug and distributor.
Try spark plugs and spark plug wires. Unless you just changed them. Possibly distributer cap and rotor if that doesn't fix it. To really fix it right you should probably pull all plug wires off one at a time and see which one is not firing. Then pull out the plug put the wire back on it and see if it is sparking while cranking it over. If you have spark, it could possibly be an injector problem. Please rate my answer.
Cylinder #2 is the the second spark plug counting from the right to left.

Your misfire can be cause by couple of things but the cheapest way that you can try to fix your car is to do a tune up by replacing:
1)all spark plugs
2)do a oil change
3)spark plug wires
3)distributor cap and rotor
note misfire can be cause by:
1.bad gas
2.spark plug and/or wire
3.distributor cap and/or rotor
4.valve adjustment
5.injector
6.off timing
7.ECM
8.bad wiring(power, ground or feed line)
You have a timing problem. Check for loose/broken belts. also see if the distributer cap is worn out or cracked. Replace it if it looks worn out. Change spark plugs.... Sounds like a typical ignition problem. If your handy, you can do this all yourself. Change plugs wires and distruber cap.
hi there, you need to make sure all wires to spark plugs are tight and very snug, you will also need to check the distributer cap to make sure no burns are on it, and make sure the plugs are in proper firing positions, the spark rotation might be out of sequence.....also make sure spark plugs are clean of all oil, and dirt, firing pin in distributer cap might be bad.....hope this helps....shia
A full tune up consists of spark plugs, distributer cap. wires. rotor for under the cap, air filter and if you want you should change the fuel and oil filter. I hope this helps.
