hi guys, my discovery (2202)is driving me nuts!!!!!!!!!! ,
A couple of months ago (nov07)we did a complete tune-up including new spark plugs and wires, some of them were failing and everything was working perfect.
All the sudden it started failing again. We changed thewires again andit only got worse.
I took the car to Auto-zone for computer reading and it says "random misfire in 2, 3 and 5"
Could it be the coil instead of the wires?
Any way we can define what it is?
If it is the coil, would it be crazy to change it by ourselves, because of its locaation?
Any comments are highly appreciated...
thank you, thank you, thank you

 

What wires did you use (and plugs)? People seem to have pretty bad luck if they use cheap wires. What type of gas do you put in it?

 

"DITTO", also what gap and what gas are you using?
