Message: [QUOTE="JCart, post: 1138300, member: 1238"] So the fuel filter is clean yes and no codes came up? I'd unplug the wiring harness plug to MAP sensor and see if she runs better. If it does you may need a new one, should have thrown a code I think though. You might also clean the fuel return screen inside fuel bowl drivers side, take out the f filter. Use Q tips and flash lite and small mirror to get at the small screen, it's about a 1/3 way down bowl inside. When clean you should clearly see SS screen. Dip the Q tips in diesel, if not done before it will take a bunch to get the Keerap off the screen. And finally any up pipe exhaust leaks or leaks at the head to exhaust manifold interface, be sure to check drivers side at the rear to ensure manifold exhaust bolts are in good shape. The bolt heads some times can pop off this is not uncommon and then the manifold to head interface will leak. Look from the underneath side with flash lite to see if there is any black carbon on the head to manifold area and also behind turbo for leaking up pipes. Cheers jrc [/QUOTE]
