anyone ever have problems with a vacuum leak on the drivers side bank, maybe a warped manifold. Long term fuel trims on that side are way up (23% enrichment). injector pulse width at 3.6ms. fuel trims on bank 1 are normal. no codes yet but idles terrible. drives just fine. compression at 140psi, plugs look lean on all 3 cylinders of bank 2. no misfire on the ignition or injection systems. checked cam timing and everything is in spec. tested for leaks, none apparent. o2 sensors functioning normal.
