Re: car will not start please help
i sprayed into the throttle body, i just went out now an after it seems to sit awhile it will start back up an run fine till it get warm an the it died out again, its throwing code 22 an 33, i replaced the throttle pos sensor,wich i think is the reason it was throwing 22, i never did unhook battery after cleaning mass air flow sensor an replaceing tps sensor,how do u test the mass air flow sensor to see if its bad or not, thanks for the help guys , this site rules)

take the iac out and clean it real good, that might take care of it stalling when it gets hot.

Re: car will not start please help
yes it can cause the car to stall if the iac is not working properly due to gunk built up in there or the iac being faulty. and yeah i would clear the codes, if for nothing else just to see if the ses comes back on.

Re: car will not start please help
Mine did something similar and it wound up being an injector that would short out after getting hot and not let me restart and then wouldn't start at all. It would run if I sprayed ether or gas into the plenum for a moment.

Do you get spark yes/no?
are there intake or exhaust obstructions yes/no?
are you getting enough fuel yes/no?
