I tried to change coil wire and now itdoesnt idle right. its up and down. any suggestions on what i did wrong?

 

check connections, and if everything checks out put the old one back on to see if it goes away.

 

i did put the old one back on thats when it started doing this. the new one it wouldnt even stay running

 

got it running. Thanks for the advice. Would it hurt if I couldnt change all my wires out at the same time? The car currently has MSD super conductors 8.5mm on it and Im going to be putting Accel 9000 8mm. Im not sure if the different brand or the different sizes would hurt anything or cause it to run poorly. Thanks for the advice in advance

 

it wouldnt hurt to wait til u do them all really. thats what i would do. i dont think there would be a benifit in changing a few unless they are any damaged. i have ran different types at the same time before tho with no problems at all(cant speak for every type of wire or car), but i didnt have a choice at the time

 

the number 1 plug is running rich so hoping changing the wire will fix the problem since changing the plug didnt fix it

 

could be the fuel injector also. some seafoam in the tank wouldnt hurt either.

 

ive ran seafoam in the tank and through the vacuum adv intake line. I know the injectors could need cleaning or what not but plugs and wires are cheaper. so if its not going to hurt it to change some without all even though they are different types and sizes off wires i guess Ill do that. Ive only changed 6 of the 8 plugs cause I cant get to two of them

 

did u have this problem before u changed ur 6 plugs? u should at least have the same brand and number plug in all cylinders

 

bosh plats are the two i havent gotten to yet. gonna have to get someone to do it when i get the cash. yes i had the same running rich issue before i changed the 6 plugs. thats what lead me to do it. it looks to be only on cylinder one
