Question about 1999 Honda Accord
The hissing could be a vacuum leak. Depending on the leak it could be a EGR valve issue, manifold gasket but you also need to check the fuel lines, pump and filter. It could also be a bad catalytic converter.

Just replace a fuel pump myself and had the same problem. I found that the wires going to the pump inside the tank where grounded out. While setting the pump in the tank I got the wires pinched between ths tank and the cover. Hope this helps.

I would talk to who cleaned the injectors, I don't know if it something they did or not. It could be a stuck open injector. The exhaust would have a raw fuel odor if it was. What it sounds like is a blown headgasket, which can just happen. The exhaust would have a sweet smell to it. Usually starts as a small leak (between cyl. 2 & 3), the engine burns the coolant while driving which you don't see. Then the coolant level gradually drops to a point where the car overheats, which warps the head, causing a large leak. Now you see the coolant burning (white smoke).
Good luck Honda Al

Testimonial: "Thank you so much for your help. I did find out the problem. I had a bad distributor cap and rotor. Got it fixed and now the car runs fine."
Possible injector failure. locate by disconnecting injectors one at a time. The one that makes no change is the questionable. Status of spark plugs need chkg also. pull the plugs an the one that looks washed is questionable good luck

Have the Idle Control Solenoid Valve cleaned up.
Or it might be defective. See steps below to check...

Try to check out the Idle Air Control Valve, it could be dirty or defective and the vacuum lines if they are not leaking. If that does not solve it have the Fast Idle Thermo Valve checked.
