My power steering seems to stop working at low speeds and there is no leak the problem is getting more frequent and I don't want to ruin the pump I looked at some other posts and it maybe just the screen needs to be cleaned but sometimes when I manually unlock the car the drivers window rolls down and the locks unlock and lock sometimes too so I'm wondering if it's an electronic issue? Thanks for the help

This is the 1st time to happen, where could the short or connection problem come from?

first time this has occured

It takes 3 turns of the key to start, afterwards car revs fast and snatches while going into gear.

car snatches when going in gear, and accelerates in low gear

If I start the engine, it cuts as soon as it started... If I start the engine and step on the gas to pic up the refs slightly, then it idels.. But if I leave the gas it cuts or it idels but so soft you don't even hear the engine running but the engine is shaking....
Can it be the plugs..? Or what would you suggest
