Sounds like intermittent misfire, don't have a clue how someone behind you can tell one side from another when they smell the fuel, the smell is likely unburned fuel effecting the cat conv, helps if is malfunctioning when testing for source of misfire, why would you do a complete and not replace old injectors and coils?
didnt have much money to do the build. it was an emergency thing. broke 3 spark plugs in head so puled the head off and found a hole in one piston. just bought a kit with pistons rings rods and crank and did it that way. took the heads into napa and had them redone. guess i figured the coils and injectors would be ok and would be easy to change latter when i did have the money to do so and you can tell which side when its sitting idleing. my engine light just came on today had it tested and said map sensor from what guy told me and something about cyl number 9 and o2 sensor but he said change map and those codes should go away. but didnt gurantee anything. which those engine test i heard werent to accurate. was hopeing someone else had same problem.
