Default PLease help

I have a 01 ssei superchargered with 144000, everything has been going lately. Ac compressor froze so car wont start, heater core, batterry, ignition module. Just today it started acting wierd. Its kinda skipping a beat when i drive on the high way it is very noticable. I got it scanned at auto zone, P0336 code is up and a o2 sensor, but the o2 has been up no activity for a year. This Crankshaft position sensor a P0336 is a new code. I usually do most of my own car work, i have limited kowledge and work in my driveway but i have some knowledge. Is this most likely why it is skipping, the crankshaft sensor. Is it going to cause any serious damage if i dont do it immediately and drive it for a few weeks? Also how hard or how long should it take to change?

Unrelated my oil pressure shot up a few months ago to 120 max, i know it the oil pressure sending unit. If i drive it without changing that will there be any long term problems. Thank you very much for ay help you can offer. My email is [email protected] and again thank you

The oil sending unit will not have any long term problems.
The crank sensor could leave you stranded but not cause any further mechanical damage.
And the O2 sensor will cause the car run rich/lean, engine shudder, poor milage, loss of power etc.

Welcome to the club, hope we can get your car back up speed

Default sensor

So you would guess its the o2 sensor making it shutter, hesitate, slip not the crankshaft position sensor? How diffecult of a job is thi crankshaft sensor? I know the part is $30 just wondering the book hours and if it would be worth having a mech do it...

The Crank Position Sensor (CPS) sits behind a plastic shield, behind the crankshaft pulley (Harmonic Balancer). Assuming yours is essentially the same as a '97 ......

To replace it: Jack up car; remove RF wheel and inner splash shield. Loosen (don't have to remove) drive belts; undo pulley bolt with an impact wrench or by holding the flex plate as the big pulley bolt is undone with a big breaker bar and a cheater. Remove HB using a puller and three 6mm x 1.0mm pitch x 70 - 80mm length bolts and washers. Pull the plastic shield off the special bolts (it snaps back on). Unplug the electrical connector (check wiring for any damage) and unbolt (10mm wrench) the CPS. Check interrupter rings on HB to make sure they are tight and straight. Reverse to install.

Figure two to three hours if you have never done it before, 40 minutes if you have.

A bad O2 sensor can cause strange symptoms. When I replaced mine with a Borg-Warner sensor, there would be times driving on the highway where it would appear as if the engine had shut off, although it had not. Stepping on the accelerator slightly produced no response. Either backing way off, and the accelerating, or stomping on it would finally make it go. I even took the car in to have it scanned for problems to try to find the cause, as well as discussing the problem with a few mechanics, with no problems found. It wasn't until it went all together and threw a code, that I found the problem, and that Borg-Warner O2s don't last any longer than the Bosch. Replace the O2 sensor with either an AC/Delco, or Denso, and see if that problem goes away.
