Lately I've been having electrical problems with the 87 NA Auto. I finally noticed that someone extended one of my power wires with three different awg of wire. I fixed it yesterday and started the car but it died immediately. Tried 3-4 times and the same thing kept happening. It was as though TPS was cutting out. It doesn't make sense for it to be the TPS because to get it going I had reved the car up to 4000rpm then waited for it to come down and put it in drive. Then I was driving down the street and I noticed the car was not shifting up at 45-50mph. I thought I'd click it into Neutral and then back into drive so that possibley the gears can catch. The second I put it into neutral the rpm went down to zero and car shut down at 45 mph. No power steering , power brakes, nothing. Ever since I restarted it I've never had that problem with it cutting out that night, however I did have a problem with it not shifting past 45-50 mph. Someone help! Are these problems related?
