Check you average consumption at speed against the manual.. Don't let it go on if you get stuck in traffic a lot as it will make your piston walls wear out early.. Extra gas will cool an engine down - but if it thinks it's running cold - it'll give it extra gas because it just thinks you are living in the Arctic and taking extra time to warm up.. Temp sensor - Thermostat - or - your injectors are dirty and leaking.. The crap they sell you to put in the tank to clean injectors isn't really useful in my experience - you should pull - all - of them out, flush the lines and bench clean.. A guess - but - a guess.. -- J Dexter - webmaster - all tunes - no cookies no subscription no weather no ads no news no phone in - Real Audio 8+ Required - all the Time Radio Free Dexterdyne Top Tune o'be-do-da-day Stan Rogers Live - Barrett's Privateers
