.constant bucking under several different circumstances
Three times I have had this car to the dealership. They drive it with the computer but nothing shows. It starts bucking ang bucking going up an incline first at 43-45 mph. Sometimes on very high roads with low dip and high inclines it will also start at 57 mph.

P0022 code also refers to camshaft (CMP) intake /left/front bank2--timing over is messed up===causes valve timing--engine mechanical fault---CMP actuator. I would re check the timing chain marks as it appears that it may be out a tooth or two. IF you have installed after market parts then the cpu may not be recognising the parameters of the part and recording a fault or trying to adjust to suit the readings which is upsetting other sensors. Check that the cat converter is not broken and blocking up the exhaust pipe
I would check the battery terminals to see if they are loose...then have the alternator checked to see if it is bad. Is your Check Engine light on? I had a 97 corolla that used to die on me or act erratic when driving. I wondered what the problem was since it happened at varying speeds, circumstances etc. I decided to take it to a really bumpy road just to see what would happen...I hit one good sized bump and the car shut off. Found that even though the battery terminals appeared tight, the negative cable wasn't. Tightened it up and never had the problem again.
Is it fuel related or what . when it wont restart have you tried spraying some stater fluid in it for 3 seconds to see if it starts. If it starts and goes dead it will be fuel related. Do this test a couple of times and you should get the same results. If it doesnot not it will be electrical. Distributor is what i would replace first. or coil .Good Luck!!!
The on board diagnostics only tracks sensors connected to the igniton system so until your problem trips a sensor it will not show a check engine and then be carefull because itll probably lead you in the wrong direction,seeing as how the problem previously existed. a dirty maf will not trip a code and for me the most common solution, you can clean this with electric parts cleaner and a tooth brush be extremely gentle for this part is fragile and very expensive, also check for a short under the hood like from the coil i know this will be hard if it is only an under load circumstance and if you can get an extended drive of about 5 to ten miles look under the truck at the exhaust to see if cats are bright red like coal letting you know there plugged up. I have had these symptoms for all three of these checks im giving you, may not be your solution but some quick cost free checks you can do yourself good luck
Had same problem with my 1999 Forester. Jiggled socked for months until I separated it from the lamp and noticed part of the socket had melted and cracked. Checked internet for socket and hoping I wouldn't have to spend big bucks for whole light assembly just to get the socket part. No luck. So called Subaru dealer in Richmond and was told that Subaru doesnt make socket anymore. The good news is they puchase universal standard socket in piggytail form. So for 8 bucks, I got the univeral socket and spliced into existing three wires and works perfectly. The guy at the dealership parts department, which is different from service department, said that they routinely sell the sockets since it is a know problem, of which models not sure. Didnt purchase one for other headlight, if it goes, since guy says they stock the part all of the time. Sounds like something you could get from electical stores, etc. besides Dealership. Hope this helps. BTW, got screwed on the bad headgaske problems...wasnt under warranty and total near 2500 bucks. Their solution of adding coolant conditioner is a con job.
Possible solution to stalling '99 Buick. My '99 Buick Century would die for no apparant reason with no error codes. After 4 days at a Buick dealership and many frustrated mechanics, the problem was corrosion from under the battery location. The wiring harness had small amounts of corrosion internally. Check the wiring under the battery for any corrosion. This has been the problem on more than 1 vehicle that we are aware of. No service bulletin has been issued by Buick.
