So I bought this pickup a few weeks ago and it was smoking white/blue bad. Turned out it had a bad injector, so I get a new set put in and get the pickup back and it will still do it. Let's say its operating temp and I leave a light, it will smoke through the intersection then clear out once u get on it. Smokes like a pig at idle as well. No idea what to do. Only have +50hp injectors and a 4in cali compliant exhaust system still has the cat. Running on road diesel with anti jell additive.
