jragsdale262 Posted October 8, 2005 Report Posted October 8, 2005 In park the car sounds terrible until 2500 rpms, then sounds normal all the way up through the rpm range. A couple of my friends think its lost compression (240k miles on engine). Replaced plugs / wires already. Went to 10W 40 oil to try and compensate. Any other ideas? Quote
Turbocharged400sbc Posted October 8, 2005 Report Posted October 8, 2005 The older 2.8 and 3.1 engines are known for dead/nearly dead injectors... Pull the upper plenum off and ohm out the injectors...you should see all of them at or near 13-16 ohms...I've seen bad ones short out (0 ohms) or damn near open (20K+ ohms) compression loss is also a possibility, and easy to test for... good luck Regards, James Quote
