Friday I had gone in the engine bay with a engine cleaner, large brush, and a hose to clean up the engine bay. I cleaned pretty much everything.

I get back in the car, and it took a little long then usual to start up, then once it did start it ran like shit, would hardly idle. I popped the hood and noticed that I acidently unplugged a spark plug wire. I hook it back up and it idled better. Thought I fixxed it.... I was wrong.

So now, after not driving the car for over 24 hours, I drive home and I noticed that when the car is under somewhat heavy load (like doing 30mph in 4th gear, and flooring it) the motor chugs, almost like the car is bucking...

It does this in any gear under load, or around full throttle. BUT if I keep the rpm's up and the car moving fast, it drives fine.

It never didi this before. What is it? I need it fixxed asap.
