does a misfire happen from driving it too hard or is it random and can happen to anyone? or is a misfire enduced from anything else

 

miss fires done just randomly happen, ive had my truck for a little over a year now, had one miss fire only because the rubber seal (o-ring) was worn out and broke or whatever, and it rained and water got in there, hooked it up to a computer and figured out what cylinder it was, got online found out the order of the cylinders (lol) took that coil pack off and replaced that rubber thing, took a air compressor and blew out that water, and dried off the plug, put it back together, and everything was good

 

anything can cause a misfire. alot of people can have a misfire and not even realise it until they throw the pedal to the floor and it just shakes.

 

yea my dad is going nuts on me saying that i did it because he "knows" i drive it like a ferrari....when i drive it very "grandma like" most of the time...haha....it threw a code when it happened but since then i reprogrammed my truck with my superchip and cleared the code like an idiot so now i dont know which cylinder it is.....is there a way i can find out or do i have to wait for it to throw another code

 

you can either wait or you can have the truck running and pull each of the coil plugs to see which one isnt making a difference.

 

while it was ating up today i just decided to hell with it and i plugged in my programmer and it threw a code even though the light had not come on....its cylinder four....so i need ot just replace the plugs and the number 4 adn 7 coil?

 

mostly likely that will fix the problem

 

cool...dude when are you gonna be at the next meet

 

ill be there this week hopefully. i dont think im going out of town, and as of right now i dont have work. i hope to have the interior on the truck finished by then.

 

badass.............so should i replace my wires too...........and area ll spark plugs the same or are there better ones? i heard for my truck i need to use motorcraft ones....and same question for the wires...are they al lthe same or are there like "performance" ones

 

You dont have wires you have COP's *Coil over plug* insted of 2 coil packs you have 8 coils going right into the spark plugs. Use Motorcraft plugs other wise you will have alot more miss-fires in about 3,000 miles. As for the COP's on Ebay alot of guys on here use global COP's

 

yea i found out i didnt have wires this morning lol and i already knew aobut the motorcraft.....thanks alot for your help and i heard its a PITA to do so should i get it done or jsut do it?

 

its not as bad as it seems. but it does definately take patience to do the plugs. the only pita is if and when you break a plug.

 

man.....do yall think it could be a leak in my vacum hose perhaps?

 

thats also a possibility
