    Ok ill add to this question I have a missfire code on cylnder 5 and it only happens once in a while like we are talking once for five minites at say 200 miles into a trip . I purchased a analyzer and got the DTS code of misfire three times . Would this be a connection of some kind?

    I put my 1998 GMC C1500 P/U into a hard acceleration situation, and the "idiot light" came on.  I continue to drive the P/U and eventually the light went away.  I have noticed that the engine seems to run a little knocky at idle but nothing that you wouldn't expect from a 98.  Higher rpm no problem, no loss of power.  what's up with my truck

The poppet valves foul on dirty fuel easily. This was a common problem amongst the first Vortec engines 1996-1997 maybe some later. You can have them cleaned but the cost of the MFI replacement GM produced ia almost as cheap and works a lot better

Has p0300 code misfire cyl 2 and 3
If it was just cylinder 2 or 3, the code would be 0302 or 0303. Instead, you have random misfires (probably) such that you should be checking things that affect the whole engine. Vacuum leaks, bad plug wires, bad coil(s) or ignition module are most likely, but even clogged exhaust, O2 sensors and bad battery can cause these problems. Yes, a battery can be good enough to start your car but still be bad enough to affect performance. If I had to guess, I would start by testing the ignition module. Most parts stores can test this if you remove it and carry it to them.

97 gm 5.7 Tahoe misfire originally on cylinders 2 and 8 changed spark plugs wire, distributor cap and rotor, then misfire went to cylinders 3 and 5 on scan
Check your coil pack. Sounds like one or two need replacing.

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

4.valve adjustment
5.injector

7.ECM

Running rough. Service engine light comes on at start and flashes after engine has run a few minutes. Computer says #6 cylinder misfire. Replaced plugs and wires. No change. Any suggestions? Also, does...
it should have a distributor, along with a external coil pack. be sure to check the inside of the distributor cap, it could very possibly be cracked , and check for arching, and the rotor also. hope this information has helped you out.

I dont remember in what order from #1 plug to#6 do the wires go? on chevy 4.3 L
Firing order 1,6,5,4,3,2. To find number 1 plug at distributor set timing mark to top dead center on compression stroke and with distributor cap removed rotor will point to number 1 cylinder in cap. Also number 1 cylinder is on drivers side all the way to the front the next cylinder behind that is number 3 and then 5. So passenger side all the way from front will be 2,4,6 at the firewall. Number 1 plug wire will also be the second longest wire in most cases or as long as number 2 cylinder. Hope this helps.

We've replaced the distributor cap and rotor in our 1985 Chevy C10 305 V8 and still have to fire TO the plugs. It won't start
This is a one piece distributor. It has the coil and pickup sensor all built in. Check and see if you have 12 volts on the large red wire that plugs into the cap while the key is on. (The other wire is for a tachometer if you have one). If you have power and there is no spark from your ignition wires, your pickup module is bad in the distributer. Very rarely have I seen a failed coil.

Chevy k1500 5.7 v8 wont start
Sounds like your timing is off when you placed the distributor back in or your spark plug wires are crossed. Start with the simple and check the spark plug wire firing order. 1-8-4-3-6-5-7-2 Cylinder numbers drivers side 1-3-5-7 radiator to firewall. Cylinder numbers passenger side 2-4-6-8 radiator to firewall. Distributor cap #1 is at 5 O'clock and rotates clock wise. Once that is establish to be good then make sure the cylinder 1 is at TDC with the distributor rotor at the #1 position. Good luck and hope it's a crossed firing order.

My 1990 chevy pickup just stopped running.
there should be 2 clips on from the rotor housing to the cap, pull the clips off and lift the cap, you will want to change the rotor inside as well. do not remove the spark plug wires from the old cap yet...replace the rotor, it will only go on one way, and put new cap on, it too should only go one way. now, one at a time, pull the plug wires and put them on the new cap that is mounted. this will ensure that you have them in the right order.
