Emission controls are sensitive and washing engines can sometimes aggravate things.

A dirty engine isn't necessarily a bad running engine. But, when you pressure wash or even hose it down, gremlins can appear as water enters cracks and crevices in the wiring and accumulates in plenums in the engine compartment.

I would have the engine codes pulled on the OBD-II system to see what is awry, and diagnose the system from there.

Good luck to you.

Motor is running fast when i start it chock seems to stay closed engin light is on

A 2000 Isuzu would have fuel injection not a carb, so no choke is used.
You would need to get the computer checked for trouble codes, I would suspect a huge vac leak is the cause of the fast idle.

No power to my comptuer plug. I can't pass my emmisson test. Is there a fuse? where would it be??

The plug gets power from the Cigarette Lighter 15A fuse in the underhood fusebox.

1990 chevy blazer 350 ci throttle body fuel injected . the motor is flooding out u can see the injectors keep dumping fuel into the throttle body

Sounds like you have an injector leaking. Have someone just cycle the key on and off to run the fuel pump but don't crank the engine. If you see fuel dripping from the injectors, unbolt the injector cover on the throttle body, remove the injectors and replace the orings around the injectors.

Ford focus 1.8 tdci, is terrible at starting when cold. The motor is slow to pick up speed and doesnt seem to spin fast enough. The glow plugs only stay on for two seconds. However once the engine is hot...

u should check for a coolant leak just above the starting motor, it makes its way into the motor gumming every thing up ,coolant leak is usually from the thermostat housing.

Check engine light coming on and going off

Probably an Oxygen sensor is slowly going out, or something small like thatm had to be emmissons/ elcetrical though....Assson as it comes on go to Advancedauto they will do a diagnosis for free most times, if you have the ob1, or ob2 system, which you do! Also check the gas cap, i know it sounds crazy but a loose gas cap can send off the CE-light, and do other crazy things...Hope this fix's-ya !!

Fuel leakage

hi the fuels expanding in the tank check the emmissioms side of things as it would appear one of the valves on that system is not opening or you have a trapped pipe not allowing the gases to filter through the emmisson system there is no engine light on by any chance if so that will tell you which valve it is but they usually come on when there is a leak yates210456

Some of the warning lights stay on.

so all the lights that come on when you first turn the key on stay on? maybe your alternator is not working properly? or not connecting to your dash panel correctly? or maybe the engine management system has a fault in it? more likely to be a dodgy connection to your dash board.
