Engine Performance problem
2005 Dodge Caravan 6 cyl Front Wheel Drive Automatic
low power developed over couple of months. Had cam sensor code. Changed cam sensor, no codes returned but no improvement in power. Feels like lack of fuel, no servicable fuel filter so changed fuel pump module. Fuel pressure constant at approx. 55PSI. Even at full throttle full load and still no codes. Map sensor readings seem to be correct, cam and crank sensor sync signal. Doesnt seem to have restricted exhaust but disconnected in front of cat. To proove. No noticeable improvement with performance decreasing greatly within seconds due to impropper O2 readings. Cam to crank differintial runs 15-18deg. Is that normal and if not why hasn't it set timing code? Thanks in advance for any info.
