Patient: 2007 Suburban 5.3 with 200K miles
Already have a AFM range 4CYL disabler installed, Already replaced fuel pressure sensor and did AC/Delco platinum plugs and walker thunder core wires, Tons of Fuel cleaner also
Oil pressure is at 25-30 on gauge and engine vibrates at idle. Most times around 25
No check engine light showing
Oil: Currently running 10W-40 Carquest HM full syn with hy-per lube oil stabilzer in her
M1 oil filter
Do these GMT 900's also have the common Oil pick up tube low pressure issue that the previous gen GM trucks have ??
Any ideas ??
