I had a question for the people of the forum. When I first start my 1991 RS with a TBI 305 and about 150K miles, and for the first 20 minutes or so, I get some serious power fluctuations, it dies way down, drops about 1K RPM then goes back to normal, maybe a little over for a second and it happens almost constantly for about 20 minutes. It looks like the injectors are good, I just changed the fuel filter and that didn't help. Any ideas? Anyone with the same issue? I want to take the almost 1,000 mile trip to Third Gen Fest '13 if thats happening next year and I have to get this issue fixed before I start making the car look nice. Thanks everyone!
