ok so first of all I drove my car through a huge puddle, It was dark and I didnít notice how deep it was until the car started to sputter. I made it to my destination then as soon as I stopped it died. when I went to leave it started up and I drove home with the sputtering prob.
Now the car has a misfire and a vacuum leak also came up on the computer, it runs and drives ok, I can start it in the morning and warm it up and it will idle fine but after I drive it and put it into park the rpms go way down then jump way up and it does it until it dies.
Iíve taken my exhaust off except for the headers to check for water, replaced the mass air flow sensor and Iíve done the plugs and wires. I have yet to do the 02 sensors or the tps sensor, other then that I donít know ??
could a vacuum leak create a misfire ?? and if so why wouldnít it do it all the time ?
any advice would b greatly appreciated..
