Cracked cylinder head could cause that as could a leaking head gasket.

YOU COULD HAVE CLOGGED FUEL FILTER AND FUEL INJECTORS.ALSO CHECK TRANSMISSION FLUID.IF LOW TRANSMISSION WILL SLIP GOING UP HILL.NOT ENOUGH FLUID TO BUILD UP PRESSURE FOR OVER DRIVE.

Testimonial: "Thanks alot for ur response i hope thats the problem and nothing bigger"
SOURCE: ok i recently changed spark
Did you mean coil the 1994 3.1 did not use a distributor , sounds like a bad coil pack and cylinders #3 and #6 do use the same coil. I would also check 3 and 6 plug wires this system is a waste spark design meaning when # 3 coil fires it is supposed to go through #3 plug wire , through #3 plug ( ground) through the engine block through the #6 plug then through the #6 wire then back to the coil, Then when #6 fires it works the opposite way, so in theory you could have one bad wire affecting 2 cylinders .....

The steps I'm going to outline are the same as we use in my shop for hesitation, sag and stumble.
All of the tools required can be borrowed from AutoZone at NO COST!
The sensors can be checked with an OBD-II code scanner borrowed from AutoZone. Pay special attention to an TP (Throttle Position) warnings. The sensor can be manually checked for binding or sticking.
Check the Heated Oxygen Sensor (HO2S) found near the firewall and screwed into the exhaust manifold for signs of corrosion on the threads. That will cause a faulty ground.
Here's a little general information that will assist you in comprehending the readouts from the code scanner. This is simply for your edification. You may be aware of all this but we've never done business before and all assumptions are off the table.
For an engine - make that any engine and irrespective of manufacturer - to run, you need three things to happen inside the engine, compression, fuel and ignition, without any one of these components the engine will not run.
If Your Engine Cranks but Does Not Start Follow this Troubleshooting Guide (This doesn't necessarily pertain to you but it's useful to know)
Most vehicles operate by the same principle; basic troubleshooting procedures apply to most cars.
The reason you should repair non-related codes after the engine is running is because sometimes false codes can be triggered by the engine not running. Once the engine is running again the code present might cycle and turn itself off. You might say "if the engine doesn't run shouldn't it have a trouble code?" Sometimes conditions occur that will not be detected by the computer, example: if the fuel pump fails the computer cannot detect the failure, so the engine doesn't start and the computer thinks everything is okay with no codes. If no trouble codes are present proceed to the next step.
Unfortunately, space does not permit me to guide you through the remedy for every code. However, the Wells Company offers extensive code diagnosis application information and technical support via its Tech Line at 1-800-558-9770, as well as in-depth product and repair videos at www.repairpath.com (use my personal access code carrepair) and through the "Wellstech" channel at www.YouTube.com

SOURCE: Hesitation on acceleration
Most common problem is a failed mass airflow sensor. Remove sensor and carefully inspect the sensor for debris building up on the diode. Another possibility is the egr valve may be partially stuck open. The upper intake manifold is made of plastic. The egr gases enter the intake just behind the throttle body inside the plastic intake. It is pretty common for the hot exhaust gases to burn through the plastic and possibly cause coolant to enter combustion chambers. A restricted catalytic convertor from previous engine misfires will accelerate this due to exhaust gases having no place to escape.
