black smoke from exhaust, jerking?
Ok new problems with my 91 Z32. When i accelerate hard the car will jerk 2 to 3 times like its struggling to move and it pushes out black smoke while doin it from the exhaust pipes. When i drive without accelerating hard it drives fine but now my suspension on the drivers side is starting to make lots of noises like the passenger side ii stated on my last thread. Just recently there was an unexpected thunderstorm and it hailed and i hydroplaned a couple times scared as hell that my car is gonna mess up. Do you guys think the water could have caused any damage? Anything i should look for?

You have a boost leak. Hard acceleration is causing the boost to leak out. THe MAF has metered the air but with the boost leaking out its throwing in more fuel and not getting that air, making it stumble.
When you accel lightly its not leaking out boost and can compensate enough. Thats USUALLY the cause of that

Lolz thanx sam and grimsta. I actually found out i wasnt leaking boost. It only happens during wet climate and i think its because when i accelerate hard in wet climate my tires struggle to find traction.
