temp sensor sitting at 60 n moving up slightly occasionally.. awful mpg.. i mean like going slowly round and used like almost quarter of a tank getting back from work and driving to a friends house reasonably locally! sounds like coolant temp sensor maybe? does this sound about right before i buy one? also the person who fitted my brand new forged engine took out the knock sensors so i couldnt use boost.. till he plugs them back in and the engine is ran in.. would this affect MPG? also.. this next one isn't costing me but its embarassing! i have to sit there for like 5 mins flicking the lights on and off.. they will flicker and go off.. then one will come on and stay on.. keep flicking away and eventually they will both stay on! right nightmare! any ideas?
