My first problem is that when my engine is cold the engine seems to act like its cutting fuel. I tried fuel injector cleaner, while it helped and made a noticable difference in throttle response the problem did not go away.
My second problem is my idle is rough and the rpm's drop. Would a grounding wire kit eliminate this problem? Are they hard to install for a first timer?

Your throttle body is probably full of carbon causing it to not open or close the whole way have it acid dipped and cleaned that should solve the problem

Alright cleaned out the throttle body, problem still persists. This usually happens around 4200rpm and the car acts like it is cutting fuel

Try using some Seafoam to clean out and flush your entire system. It does wonders and is like $5-6 a bottle. So far ive only used it in my oil, but it had my car smoking white for about 15min till evreything was burnt out and cleared. Note, your gonna have to change your spark plugs soon after doing so cause they get filled with the grime.

you could have a clogged fuel filter, sometime is something as simple as that. also check your IAC valve, that may cause an idle problem.
