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
It is odd that there is no error code retrieved and you have the theft and check engine light on at the same time. If this was related I would advise to check the voltage being supplied while off, when idling and when reving up. Security devices would need a minimum voltage for it to run, normally higher or equal to the minimum requirement for an engine to start. When off the battery should be at least 12.7v, 13v when idling (no other electrical on) and even higher when reving.
The rich issue and the check engine light may also be an isolated case. You may want to check for vacuum leaks, leaks in the intake from the air filter to the intake manifold. You may just need to have the intake sprayed with some cleaner. Have the MAF sensor sprayed with tuner cleaner.
mcdevito75, 92 Octane gas I don"t think the Navigator calls for that high an octane gas, double check on this with the Navigator dealership. The check engine light usually warns of one of the engine sensors gpoing bad, but it could be your Navigators computer is readind info input from your engine wrong due to the wrong octane gas you put in. only way to tell is have your local auto repair shop run a scan on the computer and sensors. The rust in the tailgate, water getting in and settleing in the tail gate, have the shop check out and clear or make drain holes in the tail gate for any water to get out.
take the car to dealership and get them to cancel the fault memory of the engine control unit. Then if the warning light comes back on you will need a full diagnosis check to establish what is causing thefault.
Go to library and get an automechanic's Diagnostic and Repair book or manual. Simply check out the possibility whether the negative response that you are getting from your car matches the mechanical data found in the repair book and manual.
AND NEVER forget to consult an attorney for FREE advice concerning laws governing the legal responsibilities of auto mechanics (there are attorneys who do NOT charge a fee for the first 30 minutes of advice) Check yellow pages. GOOD LUCK!
My '06 Corolla's CHECK ENGINE light came on the other day and then went out after about a half hour. It was back on this morning and stayed on, and I noticed that the automatic transmission was shifting a bit more roughly than it ever had before. Took the car to a Toyota dealership immediately. The guy told me that Toyota has had an ongoing problem with the CHECK ENGINE light coming on due to a faulty CPU (car's computer "brain"). This has been affecting models from '05, '06, and '07 according to him. He said Toyota had extended the warranty for this particular part (i.e. the CPU) due to it being faulty. The warranty expires once you reach 80,000 miles, and my car has 87,000 miles on it (yes, I do drive that much for my job!). But the guy at the dealership was kind enough to put in a new CPU for free because I have been a good, loyal customer there. The CHECK ENGINE light is now off and it should stay that way.
