When at a stoplight

When it is running, it idles rough. Any suggestions?

Service engine soon light is on. Car starts fine and I can reverse. Once I go to avcelerate, the Jimmy crawls. It'll crawl at 10, 20 mph and slowly kick into gear. It "bucks" when it kicks into gear, like it's running out of gas. There is a loud knocking sound and a "swooshing" sound, like water. The odometer won't go above 3 rpm. Once it kicks into gear, the car drives fine. This happens when I first start the car and start driving. I have no shifting problems once it kicks into gear 2000 Jimmy, 193,000 miles on it. Could it need tranny fluid?

I replaced oxygen sensor, and fuel filter which were the only codes showing but no change can anyone tell me what to check next????? it happens when i try to accelerate or pull a hill. it sounds like fuel pump but dont want to replace unless necessary.

It seems to be flooded. Will start after giving it gas and trying multiple times.

so I bought a new battery for it and when I turn the ignition switch to turn the vehicle on it doesn't want to start the battery voltage is good a little pressure is good but the vehicle itself will not turn over

The overhead console used to show the gas mileage & temp,etc,
no longer displays anything.
The garage door open funation still works and shows red when the appropriate button is pushed.
I would appreciate any assistance.
Thanks

Changed fuel filter, fuel pump, camshaft position sensor,spark plugs, wires, distributer cap, new battery. I have fuel in tank, spark but still won't start and my door locks continuously click on and off. Please help me someone.

There is no smoke out of the exhaust.

have replace all ball joints top and bottom control arm pitman basically a whole front end even adjusted the steering gear box which has no leaks and both wheel hum assemblies and new shocks if anyone has an answer please reply.

When i turn the knob to the off position on the A/C it wilnot stop blowing no matter what

Also, a lifter starts to knock. What could be the problem? This happens everyime it is driven.

Randomly will not upshift and revs high. will max out around 80 kph and rpms at 4000. No real pattern or logic to it. As well when accelerating at times it will bog out. Almost feels like its not getting enough fuel or flooding. Happens at both high and low speeds randomly. Again no pattern leading up to the problem.

am getting fluid at wheels but no brake action. abs unit has been bypassed but still no brake pedal. should not such a bypass produce standard power brake systeme

I know that it's possibly a fan or radiator but before I panic just wondering if low coolant can cause overheating while idling. Sorry if it seems silly question, just have very general knowledge of cars here
