Hey guys, can you please help me troubleshoot this problem I'm having. Well I have this 1990 Mustang GT 5.0L HO. It had started to make popping noises. The MPH needle would all of a sudden begin to jump and If I would try to step on the gas to go faster that's when the popping noise would happen, and then somehow it would fix itself and when it did it would give me a jump when I didn't want it to and then it would be driveable until it would mess up again and continue to have the same problem. That was before, now the car does the same thing but now it does it all the time, It doesn't even catch itself anymore. The car seems like it's losing power, and the performance is suffering severly. It's practically undrivable now. I'm thinking that the timing is off, but what would cause the timing to change so much in such a little time. PLEASE CAN ANYONE HELP ME FIGURE THIS THING OUT, IT'S VERY ANNOYING. If you need anymore information I'll be happy to give it to you. Thanks in advance
Michael
