1998 breeze2.0l,shutters when ac is on and it is idleing,it also spark knock when you turn the wheel sharp in either direction.and finally the other day had to stop quickly and the car sparked knocked and stalled.it wouldn't start for about thirty minutes.I towed it home and it started right up shuttered for a few seconds.then it ran fine other than the normal shutter when idleing.

clunch ? clutch Are those P codes ? P0327 an P0336
The knock sensor is a piezoelectric device that produces an output voltage based on mechanical engine vibration. The PCM will retard the electronic spark timing on the signal being received. The knock sensor produces an AC signal. The amplitude and signal frequency is dependent upon the knock level. During normal operation, the knock sensor system attempts to filter out all engine noise that is not caused by spark knock. The diagnostic test for DTC P0327 turns OFF all filtering during the first 20 seconds of engine run time. If a sufficient amount of noise is detected during the 20 second test, the diagnostic passes. If no noise is detected, the diagnostic fails. Since DTC P0327 is a type B code, the diagnostic must fail during 2 consecutive ignition cycles to set the DTC.
DTC P0336
The crankshaft position (CKP) sensor defines engine position by generating an electrical pulse each time it passes by a notch of the crankshaft reluctor wheel. The PCM uses crankshaft sensor pulses for fuel delivery and spark timing.

Any CV joint that knocks while driving straight will be dangerously worn out. Most Cv joints make noise on sharp corners. This vehicle should be a rear wheel drive and if equipped with Cv joints will be in the rear. If it knocks over rough roads/bumps I would look at stabilizer links/bushings for wear and possibly the source of your noise if you are confident it is not from the engine

check any gear like the AC, timing belt, etc

Dave, the knocking noise may end up being unrelated. As for the shutter/hesitation, depending on the vehicle, it may be a filter/in-line valve. Check the pressure hoses and the outlet of the pump. Certain pump designs will have, what seems to be an extension coming off of them, a pressure valve/limiter..

The 3.8L (VIN K) engine uses 2 knock sensors.

The Knock Sensor (KS) is mounted in the engine block, where it detects abnormal engine vibration, such as detonation (spark knock). When a knock is detected, the KS produces an AC voltage signal that is sent to the PCM. The system is designed to ****** spark 10-15° to counteract the effects of varying levels of octane in gasoline. This allows the engine to use maximum spark advance to improve driveability and fuel economy.

I hope helps; your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

That sort of misfire is typical of ignition problems. Start by checking the condition of the plugs, then the wires, then rotor, and finally the distributor cap. Have in mind that a particularly black, oily spark plug doesnt necessarily means that it is shot, but also it could mean that the cable leading to it, or the corresponding contact at the distributor cap is not doing its job.

If Your Front CV shaft is broken it will not engage...Shaft can be in visibly good shape, but you might hear a knocking sound or a shutter when turning sharply. I had this problem this last winter. Get under the truck and try and turn the CV by hand. if it can be rotated, it is bad.

torq converter bolt are loose or gone

Try higher octane and decarbon engine. fuel filter good idea also. sounds like detonation

For one is your truck lifted? does it have over size tires? What year is it? is the idle normal when your not turning the wheel?
