Burning alot of Gas..

[VWDubstep]

Car seems to be burning alot of gas, I think I am getting 22mpg instead of 30 mpg

Have a new CAT, new O2 sensor..

I have a 1989 VW CIS Injection 16v Valve engine. The car just does not want to move in 1st, 2nd and 3rd gear. On the freeway in 5th gear the car runs amazing, on the streets it misses and jerks like crazy....I need some help trying to troubleshoot how to resolve this issue. Hope someone can point me in the right direction.

Try new spark plugs, spark plug wires, distributor cap and rotor. If your engine is misfiring it could be because you distributor cap melted a little near the metal. I had that problem a while ago. Only seemed to happen at low rpm's.
