Hello everyone. I have a 2001 xj with a rebuilt engine (approximately) 10000 mile on it. Ever since the rebuild I have had a rough idle and suffer from poor fuel economy. Here is a list of what I have checked replaced so far.
New plugs, coil pack and injectors at the time of rebuild.
Cam shaft sensor synced at the dealer.
New idle air controller
Map Sensor 0" 4.56, 5" 3.91, 10" 3.03, 20" 1.45, 21" 1.1
Throttle position sensor was within spec at time of test but I don't remember the numbers.
Compression test over 165 in all cylinders
Leak down test 5% drop in cylinders 1 and 2. 2% drop in cylinders 3-6
Resistance test from PCM driver wire to pin 2 of injectors: cylinder 1 injector 0.4, 2 0.2, 3 0.2, 4 0.2, 5 0.3, 6 0.1
