I have a 2002 gmc envoy,when i go over a speed bump it stops pulling.when i restart it,it starts driving fine.what could cause this?it has only did this twice.


The steering gets hard because the engine has stalled, it is not a problem but a symptom. In modern computer controlled vehicles the engine is monitored constantly for problems, when one occurs a fault code is set with very few exceptions. What you need to do is go to an Autozone or other discount parts store and ask for an OBD2 (On Board Diagnostics Generation 2 OBD2) fault test, it is free, once you have the fault codes you can post them here and we can advise on what might be the problem, in your case it is likely fuel or ignition related.

Code P0452 keeps coming up and the check engin light is on


P0452 is related to the Evaporative Emissions Control system and has nothing to do with the 4WD system.
The P0452 may be something as simple as a loose or bad gas cap.
The 4WD system is somewhat complicated and requires more diagnostics.

CODE P1870,P0420


P1870 generally means that the transmission is slipping. P0420 relates to an issue with a vehicles catalytic converter. To know specifically what each code is, as it relates to your vehicle, you should take it to a local auto-part store (like AutoZone and have them pull the codes off of your vehicle. At auto part stores, they generally do this service for free and it is pretty quick. Regards ~ JD

See or call your local auto parts store such as AutoZone or O'Reillys for the trouble code definition. Also, make sure your gas cap is really secure, and I mean tight.
