So I just bought a 1993 xj; so when I bought it it was idling bad...so I changed the sparks plugs with no luck still same problem I check for spark... Cylinder 1 and 4 are firing cylinder 2 and 3 are not I was testing the coil but I accidentally broke it... I got another one coming.. Could the computer only be sending fire to one coil and not the other one and is there a way to test that??
Thanks in advance
