p1326 is a knock sensor code. Checked oil and oil level was bellow the add level. on higher RPM or heavy acceleration rods could possibly knock causing sensor to put vehicle in limp mode. did an oil change using a premium filter with drain back valve and used high millage full synthetic oil. Hyundai recommends using fuel treatment every 3000 miles. poor fuel will also cause engine knock if injectors are not performing well. at fill up use the 2 bottles we supplied before filling tank so treatment can evenly disperse while tank fills Cleared code test drove and engine is not knocking at this time oil change should be done no more than 5000 miles 3000 is better for your vehicle

p0304 cylinder 4 misfire. removed number 4 plug and has carbon spark fouling. plugs have been replaced previously with bosch double platinum plugs. ngk or denzo double platnum/nickle should be used. plugs looked good so replaced plug with ngk spark plug in single misfire cylinder cleared codes

Ac is blowing 30/25' deg less than ambient temperature this is manufacture requirements for AC. could not duplicate cooler heating function on passenger side vent
possible internal ECM communication fault with fan module. we can turn fan on and off in low or high speeds when engine is off but when engine is running it inhibits command and fails. running AC will turn on fans in high or low. checked function of all relays and blown fuses no problems with function. swapped relays and still no difference in operation. replaced coolant temperature sensor and no difference with function as well.

ENGINE COMPRESSION – Testing – 2.5L Eng – [NOTE: Add 0.2 for wet compression retest.]
p0302 cylinder 2 misfire pulled plugs found carbon build up on number 2 plug. proceded to do compression test on all cylinders. #1 65lbs #2 35lbs #3 70lbs #4 70lbs. possible burnt valve or piston ring. replaced plugs no change in engine noise or misfire. more concerning is the cam crank correlation code p0017*95 also oil pressure a range code p054:00 p000b CMP slow response.

No oil on oil level indicator. last oil change was at 93371 miles last September. mileage is at 106k now. noise is rod knock. replaced oil with a full synthetic high millage oil. oil changes should be done at 5000 miles or less on this vehicle.
