I Have two problems NEED HELP!!
First, My car will start flashing all the codes... Like Park brake fail, dsc fail, engine fault, transmision fault... and so on, it wont rev past 2000 rpm. If i turn the car off and back on its ok for a few hours. What could be cuasing this? a loose senser?
Second, I have a weird vacume leak. Its in the crankcase. When i take off the oil filler cap i can feel a considerable vacume and the revs of the engine lower( you know becuase of air getting in without the MAF knowing) anyway Are cars dont have PCV valves so i'm kinda at a end point for now. Any ideas of what this might be would be very helpful.
Thank you.
BTW i have a 03 s-type 4.2

RE: I Have two problems NEED HELP!!
The variables with all those lights is hard to say. Has the car ever been in an accident?
The leak you are hearing is probably the valve bolted to the right side cam cover. Push it down a little with engine running and you will hear the noise change. This, btw is not causing your other problem and is going to be secondary to the first problem.
Could be a network problem, a module, a loose relay, loose ground, loose connector. loose pin in a connector. Need to know what codes are in there and if there is a module that is not communicating. Best thing is to get it to dealer without shutting it off. That way they can see the problem and scan it with fault present. If a module is not communicating, much easier to diagnose. Just tell them, do not shut it off and get it scanned right now.

RE: I Have two problems NEED HELP!!
Thanks, i will check all that in the morning.
Yeah the codes dont seem to be anything, just everything. Unless the planets are lining up and jesus is coming i dont this every senser in my car is failing at once. Same thing happend once when i was working on the car and forgot to plug in the MAF and three other plugs on the left side of the engine when i did the therostat housing. so i think i will start by cleaning those and what not. Thanks for your help!!!
Kinda a funny thing.... you said try to get it two the dealer without shutting it off.I would if it was practical. I live 50 miles from the dealer and when it codes out it wont drive over 5 miles an hour.
