i just purchased a 90 supercoupe that seemed to be the deal of a lifetime but ofcourse murphys law had to play its role i was ddrivin it today 12/19/03 and all of a sudden it started runnin on 3 or 4 cylinders whatever like crap just so happened there was an auto garage right were it started doing it so i limped it in there i called the place i bought it from knowin they knew somim was wrong with it but they had thought thyey fixed it with a tune up well we both decided it was either the coil pack or the ignition module so i asked the people were i was if they could help me out somehow well they just happened to have another coil pack assumim that was the problem especially after takin the wires off the coil and checkin for spark there was a dead hole in the coil (not sure if the was more than one not workin at that time)we stopped checkin after the one so i put the other used coil on and it did the same thing so i ended up leavin it there to try to find a ignition module well i would have to order one so i went back up to see if there was more than one hole on the coil not workin cause i was told that ignition module has 2 sides and if the coil is not firin in 3 holes then its the module when i went to check it out it started like crap and while my girlfriend was holdin her foot on the gas to keep it runnin i was chechin for spark again and it started firrin on all 6 again by the time i got done so we let it run for a minute it seemed fine so i drove it home before i got there it did it again i limped it home and started pullin off the wires on the coil checkin it again and once again by the time i got done it started runnin fine again now obviously somim is cuttin in and out but i dont know what i kinda wonder if there is a major wirin problem with it cause there is some othere things not workin wright the stereo only works on the drivers side and i have played with the head unit and the amp being its got the jbl sound system i figured either there is a channel burned out of the head or the amp well sometimes the stereo will cut out completly and it is related to hittin bumps and what not the door chime only chimes sometimes when i leave the keys in the ignition and the firm ride switch activates on and off on its own anyway i would be kinda suprised if the interior electronic problems are related to the ignition problems but it is posible i know i need to put a coder on it but any help at this point would be greatly appreciated oh yea when the girlfriend was revin it to keep it runnin and i was under the hood it also has a knock in it didnt investigate enough to know wheather it was comin from the upper end or the lower end but assumin it might be common maybe you guys would have an idea i bought the car for a grand even and it has less than 100,000 miles on it so i can afford to spend some money on it but by the same tocken i dont need to be gettin crazy with it either thanks
