having troubles with my 91 park avenue spark reference circuit codes
I just replaced the ecm,coil pack, plugs,and wires on my 91 Park Avenue. Every thing was fine untill 5 days later it just would'nt start again. So I replaced the cam shaft sensor as well as the crank shaft sensor, without using the alignment tool. Now the car runs rough and lean, and also loses all power when hitting operating temp. HELP ME PLEASE!!
Have you checked your fuel pressure? Do you have any engine codes? Running lean would have me looking for a big vacuum leak.
Sorry not lean anymore, but timing seems off and still loses all power when hitting operating temp. I still think my crank shaft sensor is out of alignment. Everything I've read through and people talked to say it'* the crankshaft sensor. I didn't use an alignment tool, not enough money to take car in to a shop.
