I passed everything on my emissions but my NOx was real high

When we drive the car for a while the breaks will start to apply by themself. It will get to the point when driving fast it will start to shake the car real bad. We disconnected the ABS but did not help. What may be causing this.

CLEANING THE RIGHT REAR WHEEL SENSOR (CHANGED AXLE DUE TO TORN BOOT) DIDN'T HELP. NO BAD SOUNDS. PROBLEM STARTED AFTER PUNCTURE IN REAR TIRE WAS REPAIRED - WHEEL REMOVED AND REPLACED BY TECH. THAT SHOP SAYS "THEY DID NOTHING". COULD THE WHEEL SENSOR HAVE BEEN DAMAGED BY THE TIRE GUYS?

Problem now for along period. Note battery will drain
if I leave it connected. don't know where to look for a short, or open. No codes read.

Had a leak in intake manifold,wich caused the crankcase to fill with oil and the car was driven for a while like this.I replaced the intaken manifold gasket,now the push rods are opening the valves slightly so theres no compression, I have them withb the 5.68 lenghts in the intake and the 6"lengths in the exhaust valves but they are opening the vallves,there is no adjustment on the rocker arm,it says to just torque the rocker arm bolt down what could be wrong?Hope someone can help.

The power operated door will not shut. You can push on it and it look like it shut but as soon as you let the pressure off of it it comes back. It is almost like it won't clasp.
