hi, i have a suzuki vitara 1997 manual g16b, my car is running super rich and i think is running in limp mode. I have replaced the fuel injectors, the fuel pressure reulator ( the old one had fuel coming out the vac hose) , replaced the ecu and oxygen sensor. still nothing changed. Removed the exhaust mainifold and found the no 4 pipe cracked, almost completly around, replaced with extractors. changed plugs, leads, dizzy cap and rotor. checked timing with freeze pin. there are no diagnostic codes. checked egr it was clean. could anyone have any suggestions what else colud be making the car run in limp home mode. The car just started running the way it is. thanks
