Hello all, I have a 99 VX and have had lots of work done recently and am at a standstill as well as the "isuzu certified" tech/mech. I recently had the engine re-manufactured at 130000 miles and was running rich on the drivers side after reinstall. The mechanic said it may be the computer? Got a used one because the old couldn't be updated? Now and for the last 2 months, the mechanic has chased fault codes and checked everything we can both think of and it still has a cold start and won't idle down to right RPM. It starts, and thought it was coolant temp sensor or thermostat but everything checks out. I don't know what else to do at this point, I have put too much in to this one of a kind and would hate to scrap it now. Can anyone give any suggestions?
