| 1995 Jeep Grand Cherokee |
| make | Jeep | | model | Grand Cherokee | | year | 1995 | | what | 5.2 V8 w/ vortech supercharger. No engine codes present. I have an intermitant hesitation/chugging when accelerating. I can down shift and rev out of it sometimes but it still struggles. Fuel pressure is 40 psi at idle on the stock fuel pump. With 2nd fuel pump turned on its at 50psi at idle. When the boost comes on the FMU brings the fuel pressure up 60-80psi depending on boost (5psi tops). I have swapped TPS and IAC. Wires, cap, roter are 4,000 miles old. Vehicle has crane cams HI-6 timing retart on it , could that be malfunctioning? o2 sensor? |
