Hi can anyone help me my engine warning light came on in my is200 so i took it to a local garage to be put on a diagnostic.It came up with multiple misfire on cylinders 2/3/6 he then went on to see which ones were not firing by removing the coils.He decided i needed new coils on the three cylinders so i bought them £115 each,he fitted them but engine still misfiring.So he checks compression on each cylinder which turned out ok.Then he checks for corrosion on the plugs for the injectors which are fine he also checks all the plugs which are all still sparking fine.After all this he was at a loss and dosent no what to do next this cost me the best part of £500 and do not have any money left at the moment to take it to lexus who want £115 p/h to look at it.If anyone has got any ideas that could help me because i dont want to have to get rid of it for nothing, i would be very gratefull.
