on the way to savannah GA i started experiencing an shuddering problem. with a complete tune up.....wires, plugs, cap, rotor, etc. he later found when going to test something that the negative wire was very loose which ...probably...caused a power spike which in turn messed up my ecu. he tested the injectors with an injector light and three blink dimly, on didn't blink..which means no fuel or too lean and the other lit up like a house light which made sense because the plugs was fouled and completely black..too rich. the only conclusion him and the other mechanics came too was the loose ground messed up the ecu which is messing up the injectors. these are very reliable people and not just some dealer. they are privatly owned and good people. they even gave me the option to find someone who has the same year volvo and and put their ecu in my car and see if the ecu fixes the problem. they are not just trying to take my money. if anyone has experienced this problem or has any other ideas on what this might be, your help will be appreciated. thank you.
