Hey guys I'm hoping I can get some help on remedying my situation here... I'm new to the forum by the way.
I drove my car for about 30 miles with the oil filler cap off and I started having some issues. At first the car would start and then run but eventually it got to the point of cranking just fine but dies immediately. If i apply throttle it will run until i let off. Another interesting thing is that it will idle rough if I pull the hose off of the throttle body... and there's white smoke coming out of the tail pipe and last night it was coming up through the engine... it looked like it was seeping out of the pipes right above one of the cat converters.
Here are the things I've done to it:
Cleaned the IAC valve.
Cleaned the EGR channels.
Changed the EGR tube and EGR valve (they needed changed anyways)
Changed the fuel filter (there's fuel pressure by the way)
Changed spark plugs (they also needed changed anyways)
Cleaned the MAF sensor.
Cleaned the fuel system with seafoam through the brake booster line.
And cleaned the inside of the throttle body with carb cleaner which i wish i hadn't done but my brother in law did it and thought it was ok to do...
I haven't changed the oil yet but I'm cant imagine that being the problem of not starting. I did check it and it's dark and dirty... but it doesn't look like it has water/antifreeze in it. I ran the car after replacing the oil cap for a while too.
I don't have any error codes but the battery was unhooked for a few days...
So my questions are...
Is one or both of my cats clogged?
What is causing the smoke?
Could the carb cleaner have damaged the coating in the throttle body and would it cause any of these problems?
How do i diagnose valves and sensors?
Where do i go from here?
Thanks for any help.
