engine running rough
well i upgraded my fuel injectors to the 703 neon injectors and everything was working fine and then everything went south the check engine light came on i have fouled spark plugs
one code said something about bad 6th injector
it smells like exhaust/gas when running
and i have black smoke coming out my tailpipe when i accelerate hard
and the engine feels like its sputtering
since this all happened ive changed the bad spark plugs and i put my stock injectors back in the engine still sputters like it did with the neon injectors it still smells like exhaust/gas when running
but i dont have as much black smoke coming out my tailpipe when i accelerate hard

My 97 cherokee was running ruff for months. Replaced tps iac nothing worked. Then I replace both 02 sensors and BAM ran great. No rough runs.
