My brother has a 76 2.0 that has just developed a heavy missfire. The car starts up fine and idles great. When he gives it throttle, it seems to load up and missfires. THe car is down on power to th e point that going up hills is very slow The car was running great up until this morning. We have checked the coil and have checked for other loose connections but have found nothing. We are new to these cars (my experience is with 911's). Anything we should start looking for? Thanks.
