Default Changed timing belt now have bad gas milage

Hello, I have a 2006 PT cruiser non turbo auto trans 51,000 miles, I have a engine stumble, shaking at idle. I had my plugs and wires both after market changed and it didnt help, then they told me to change my timing belt, I did that and still the same thing but now my cruiser is eating alot more gas, can it be that the timing is off? I have paid over $1000.00 and still have the same trouble that I started with, can anyone help, I dont want to keep paying for repairs that dont help. Thanks

Welcome to the forum!!

When did the stumble start, before or after plugs & wires? If it was after, I would suspect wrong gap, it should be gapped at .040. Otherwise IDK!!!

I don't know who told you to do timing belt - I've never heard of one going bad at 51,000 miles. I have over 82,000 miles on my PT now and am planning to have the belt done in the future...
Does it run okay off idle?
You may have an intake gasket leak - spray starter fluid along seam of intake gasket while engine is running - if idle smooths out, it's an intake gasket.
If timing belt wasn't put on right, car would be hard to start and really run crappy.
Another possibility is a clogged injector - try putting some good furl injector cleaner in the gas - sometimes that works.
