Hesitation at High Speed 94 METRo PLEASE HELP

[Irakli]

Not too long ago my precious 1994 Geo Metro started acting weird - engine started hesitation at high speeds.
For example after 5 minuted drive n a highway at speeds over 50 mph engine is hesitationg. My trip from wisconsin turned into a road torture.
Car would not drive over 35 MPH normally without hesitation.
I can drive in the city at lower speeds for hours but never have problem.

Please people give me some idea, help me save my gas saver.

Thanks beforehand.

replace fuel filter by gas tank and check fuel pressure

Thanks a lot for your input. I had it replaced not too long ago. I bought some cheap fuel filter off ebay brand new. Hopefully it was not defective. I may do it one more time. How about Map Sensor or TPS? just got MAP sensor and will put it in see if it helps.

By the way I just got new website: www.geometroclub.com will have it up sometimes in nearest future.

check if your exhaust is restricted..(bent & crimped, plugged cat or muffler, etc)

Put brand new exhaust all the way less than a year ago. Can it go bad that quick? Thanks though.

your fuel injector could be clogged or bad.

have you done a tune up on it recently? also might have a bad wire. and if all that is good have fuel pressure checked, pump might be weraing out

I'm not a mechnic or anything but I'd say replace or check your timing belt.
