DODGE RAM COMPRESSION PROBLEM

1998 Dodge Ram

Just had the computer flashed and replaced by a dealer. The truck (360cid) seems to be running very rich (black sooty exhaust strong fuel oder and poor mileage). I pulled 6 codes. P0171 to lean on bank 1 P0300 random misfire P0304 cylinder 4misfire P0306 cyl 6 misfire P0307 cylinder 7 misfire P0308 cylinder 8 misfire. It has a some what ruff idle but runs down the road fine. Any help will be appreciated. I would offer an donation but am on unemployment at this time and cash is tight Thanks

Why did you have the pcm replaced?

You need to start with basis like compression fuel pressure and spark tests.

Were these codes present before replacement
