Right posted once or twice. Basicly, my 2.2 astra is doing 18MPG (most people getting atleast 25-30 on here) and is jerking at about 1000 revs when im 'crawling' in traffic.
Some simple and inexpensive things to try, with out to much hastle to myself.
Clean EGR valve. With carb cleaner.
Replace fuel filter.. with new one...
Fix hole in flexi pipe. New pipe or patch.
My question being, do you guys think this will probally fix my problems? Any mechanics out there your opinions greatly appreciated.
