2004 GMC Sierra 6 cyl Two Wheel Drive Automatic 80000 miles
Oil gauge is flunctuating. When driving gauge shows 40-45, but when slowed down or at a stop, the gauge is 20-25 & sometimes 15-20. Then when speeding up gauge goes back to 40-55. If let off gas, goes down to 30 & back to 45 when back on gas. Oil sender unit has been replaced, but stiil acting the same. No noises from engine, & no real changes in how the motor runs. Seems to run ok. Would appreciate any info that might help. Thanks *
have the same problem?
