I have a 99 tahoe with a misfire on #5 which is probably an injector. But, I wanted to replace the distributor cap and rotor with an upgraded one. In doing so, I found out that the plastic distributor was broken on the mounting screws for the cap. I purchased an all aluminum distributor online which is a direct replacement and much better than the factory plastic one. My problem is that since I installed it, I've noticed my gas mileage has gotten worse. The sticker under the hood says it doesn't have to be timed. Is this correct? How about if the distributor is off a tooth, will this matter? I've put plenty of distributors in my older cars that I have to time with a light. This one, just seems a lil weird to me. What is the correct procedure to install? Thanks
have the same problem?
