I sprayed carburator cleaner in the throttle body of my 2005 nissan altima now it idles funny and is hard to start

Service air cleaner and clean throttle body. make sure throttle position switch is ok .

My best guess is gonna be a vaccum leak... pick up a cheap can of carb cleaner. Start your car and listen for a whistle or something close. it will probly be near or behind the throttle body. take your carb cleaner and spray it with out the little red hose around the back coner on the driver side of the motor. you can visually inspect the area after you hear an increase the idle. if you dont find it there spray all around any where you see a hose. Hope it helps. a vaccum leak usually wont set a check engine light on OBD 1 cars. Good luck.

Problems with Nissan 2005 Altima include-Crank shaft position sensor with ECU reset, ECU Factory reset from Dealer, Low Fuel pressure requiring fuel pump replacement, Replacement of ignition coils causing misfire during start-Catalytic Converter Recall-Oxygen sensor on exhaust-Leaking Valve cover gasket-Radiator failure due to plastic top & Bottom (Constantly adding water to reservoir?)

I think there is a recall with idle speed in that year altima. check your dealership for recalls and idle adjustment. if it has high miles try spraying throttle cleaner into the throttle body. (spray it directly in throttle body not the mass air flow sensor on the air box) when its idling. worst case you'll need a new throttle body

try disconnecting the neg batt terminal for a few mins....take the car for a spin afterwards so the computer can re-learn what it is suppose to know....hope this helps

the throttle body air valve or throttle valve needs cleaning.it has a little carbon build up.it will cause it to idle high.get gum out throttle body cleaner. remove all electrical components.also all plastic and rubber parts the gum out cleaner will destroy it. also replace throttle body gasket.

Removal and Installation To Remove:

1. Remove or disconnect the following:
   • Mass air flow sensor electrical connector
   • Tube clamp at the electronic throttle control actuator
   • Air cleaner to electronic throttle control actuator tube, upper air cleaner case
   • Mass air flow sensor from the cleaner case.

To Install:

1. Install or connect the following:
   • Mass air flow sensor to the cleaner case
   • Air cleaner to electronic throttle control actuator tube
   • Tube clamp at the electronic throttle control actuator
   • Mass air flow sensor electrical connector

To clean the throttle body disconnect the air tube running form the air box to throttle body and use Carbon cleaner. Read direction on can. Also clean EGR valve since this does control idle if it is carbon up it will cause the small valve on the inside to stick open causing rough idle and or stalling out at idle use the same cleaner.

MAKE SURE WHEN YOU PLUGGED THE SPARK PLUGS IN THAT YOU GOT THEM IN THE RIGHT FIREING ORDER,ALSO MAKE SURE THAT YOUR THROTTLE BODY IS OPERATING NORMALY WATCH IT WHILE THE CAR IS RUNNING TRY MOVING THE THROTTLE BODY ROD BY HAND

I have been having this problem, first definitely check out the throttle body to see if its gummed up and you can try to clean that by spraying carb cleaner into it, check all your filters, check the idle air control valve and spray with carb cleaner but not onto any electrical connectors, crank the car and if it doesn't start then give it a bit of gas while cranking and it will idle rough and it will smoke a bit to burn off the cleaner, and hold rpms until it the idle smooths out, if that doesnt work then maybe a mechanic?
