Driving van runs ok until rpm gets to aroung 3,000 then feels like a misfire, no codes, data appears normal engine runs good above 3000

It could be a dead spot in the throttle position sensor or mass air flow sensor while opening and closing the sensors you can check the resistance by piercing the wires with straight pins and use an analog meter to test . I don't know which wires to pierce as I don't have a wiring diagram

Battery drains while sitting

Hi Anonymous, perform the following tests:
1. Fill acid type batteries to proper levels.
2. Charge battery overnight at 1-2 amps you need 12.5 volts or better after charging.
3. Hook up battery positive cable, then with your multimeter on the milliamp scale connect one lead to the negative battery post and the other lead to the ground cable. Meter should read 3 milliamps or less, 10 milliamps with a radio, 15 milliamps with radio and CB. If your meter reads higher you need to isolate the circuit by pulling fuses and circuit breakers one at a time and observe meter for drop in aprerage then get out your test light and track down the short in that circuit.
3. Make sure all connections are clean and tight especially the negative cable at "BOTH" ends.
4. Hook up volt meter to battery and start engine, if meter falls below 9.5 v while cranking replace battery.
5. With engine running at 3600 RPM battery should read 14.3-14.7 volts if not continue tests.
6. Unplug voltage regulator from alternator at crankcase by front of primary cover.
7. To test voltage regulator go to:
8. With ohm meter, one lead grounded, touch alternator pin meter should read infinity, if not replace stator.
9. With ohm meter, both leads touching alternator pins meter should read 0.1 to 0.2 ohms on 1989 and later models. 0.2 to 0.4 ohms 1988 and earlier models, if not replace stator.
10. With volt meter set on AC scale, both leads touching alternator pins meter should read
16 to 20 volts AC for every 1000 RPM'S 1989 and later and 19 to 26 volts AC for every 1000 RPMS. If not replace rotor.

Frt rotors replace 2001 monte carl along with pads steerin wheel shakes while braking why?

You may need to re-machine those rotors as there is most likely excessive run out or warpage present causing the steering wheel to shimmy while braking. There is a limit on how much can be shaved off the rotors as these warp easier the thinner they get. I have seen replacement rotors with problems right out of the package. The only realistic way to check if one or both are wavy is to chalk them up on a lathe and see how much run out is present on the rotors.
