been driving the car just over a month since BSM delete, failed belt repair, and colt cam install.... Put about 3200 miles on it and just did a 420 mile round trip to Maryland over the weekend. Drove the car about 1 mile from the house Monday morning and while I was setting at a red light the car had a single misfire right before the light turned green and when I took off from the light it made it to second gear before it developed a full time miss!!! Drove it home and grabbed my suburban to get to work. C.E.L. isn't working so I pulled the codes and it has a P0203 for #3 inj of coarse... Now I pulled the valve cover today and the injector ohm reading was identical on all 4, grounds checked good on all 4. My question is should I keep chasing or is it typically the injector itself even though it has a good electrical check.... The dang car only has 119k miles on it so Im hoping it isn't a wiring issue this early on, haha.... That being said I hate to pay for a PD inj this early on as well!!!! thanks for any input, just trigger shy on the pricey parts, thinking of swapping 3 & 4 inj to verify before I order one. Also do most just throw one inj at it or do a set so they are matched??? if it has 250-300k id automatically just do a set if it indeed is bad but 119k is kinda low to warrant the expense...
