My 1997 Pontiac Sunfire will turn on but I need to leave it cranking for a bit and give it a little gas, it can run, but when I try to accelerate past 40mph, the revolutions drop which reduce my speed, so I can't get past 40mph. Also when I am parked and the car is on I can smell gas. Check engine is on. While I am accelerating towards 40mph it feels like it wants to accelerate faster but it wont do it, it accelerates slowly. If I "floor it" i hear weird sounds like glup glup glup, and if i do it too much and stop the car, it will stall.

I replaced the following:
Spark plug wireset
Mass airflow sensor
Throttle position sensor
I added the following:
I was told by autozone it could be the throttle control solenoid, idle air control valve, or that it needs a cleansing of the throttle body.
BTW when I try to use a computer to read what is going on, I can't get anything but that hasn't stopped me from driving past 70mph on the highway before this problem. What else could it be?
