Air and Fuel filters changed...plugs and wires... Distributor Cap...all done in this past week.
Start looking at the carburetor. Using a fuel cleaner will probably make it worse. But the first thing I do on older engines is a compression test.
Randy gas sprays in the carb then stops?? (Husband said) Compression test? And have also used Sea Foam and carb cleaner...I know he has the plug gap at .030
Compression test is pulling the spark plugs and check the pressure for each cylinder when turn over the engine. I don't know the numbers, but anything under 90 PSI is not good.

No,the cat is not the problem,removed mine,got more power and better gas mileage,what size engine do you have,when was the last time you changed the fuel filter.
Testimonial: "It's a 318 ... changed the air and fuel filter.. distributor cap..lugs and wires all-in this past week. Seems to be getting worse"
SOURCE: replace a catalytic converter for a 1999 dodge stratus
The cat is located just off of the exhaust manifold. You have to remove things to get out of the way. Loosen down pipe to converter and unclamp the converter and it should pull right out. Use a good penetrating oil to help loosen the down pipe bolts.
SOURCE: do I need a catalytic converter
Yes but there could be other causes. A sticky fuel injector, bad fuel pump etc. Other signs of a bad catalytic converter are a smelly sulphur exhaust, a very hot exhaust throwing heat from the middle of the car. Unless there's a lot of miles on your car, I'd be surprised if it were a bad Cat. Hope this answers your question. Best of luck.

SOURCE: P2097 Error code in 2006 Dodge Grand Caravan, which O2 Sensor?
The one before the catalytic, on the side where cylinder # 1 is at. close to the exhaust mag.
SOURCE: How do you delete catalytic
Than you will need to purchase a O2 Simulator that replaces the downstream o2 sensor and fools the computer into thinking the cat is there and working. There are several companies that make these. You can google search ( "O2 simulator" ) for these items and decide which one would work best for you.

Do you mean P0351, P0352, P0700? (The "P" makes a HUGE difference - it could also be a "C" a "B" or a "U") When you post fault codes, please be sure to post the ENTIRE fault code.
Anyway, P0700 is a generic code that is output by the Engine Control Module (ECM) to let you know that there are transmission faults present in the Transmission Control Module (TCM). To find out what the problem actually is, you must have a scanner that is capable of accessing the TCM and retriving the codes. NOTE: a "generic OBD" code reader cannot do this.
P0351 is "Ignition Coil #1 Primary Circuit"
P0352 is "Ignition Coil #2 Primary Circuit"
The ignition coil primary circuit is monitored when battery voltage is more than 8 volts during cranking or more than 13 volts with the engine running at less than 3000 RPM, and no coil in dwell during testing. The Diagnostic Test Code (DTC) will set in the Powertrain Control Module (PCM) memory when the PCM senses peak current is not achieved with battery based dwell plus 1.5 milliseconds of diagnostic offset. DTC P0351 and/or DTC Po352 takes less that 3 seconds to set during engine cranking, or up to 6 seconds with the engine running. Possible causes for these DTCs are : Intermittent condition, defective ignition coil (or coils), defective connectors or wiring,defective PCM .
NOTE: Intermiitent failures or problems in the contacts/circuits of the Auto Shutdown (ASD) relay can also cause these codes. Some aftermarket equipment , like remote starters and antitheft systems that are connected to the ASD relay circuits can also cause these codes. Any such equipment should be COMPLETELY removed from the vehicle before attempting to diagnose these codes.

We removed the catalytic convertor and truck seemed fine for about 10 weeks...could this have anything to do with it?
Your fuel injectors may be clogged.Here's a link on testing them,Autozone may have a loaner tool you need to test it.Usually the dealer will charge about a 100 bucks to cleanhttp://www.autozone.com/repairinfo/repai...
Here's another link on your fuel injectors Cynthiahttp://www.autozone.com/repairinfo/repai...

here's the throttle body sensorhttp://www.autozone.com/repairinfo/repai...
here's the fuel pressure regulatorhttp://www.autozone.com/repairinfo/repai...
And here's the fuel pumphttp://www.autozone.com/repairinfo/repai...
Here's how to relieve the fuel pressurehttp://www.autozone.com/repairinfo/repai...
The Throttle Body Injection (TBI) system is used on 1988 V6-238 and V8-318 engines. The system is controlled by a pre-programmed digital computer known as the Single Module Engine Controller (SMEC). The SMEC controls ignition timing, air/fuel ratio, emission control devices, charging system and idle speed. The SMEC constantly varies all settings to meet changing operating conditions.
Various sensors provide the input necessary for the SMEC to correctly regulate the fuel flow at the fuel injector. These include the manifold absolute pressure, throttle position, oxygen sensor, coolant temperature, charge temperature, vehicle speed (distance) sensors and throttle body temperature. In addition to the sensors, various switches also provide important information. These include the neutral-safety, heated backlite, air conditioning, air conditioning clutch switches, and an electronic idle switch.
All inputs to the SMEC are converted into signals sent to the power module. These signals cause the power module to change either the fuel flow at the injector or ignition timing or both.
The SMEC tests many of its own input and output circuits. If a fault is found in a major system, this information is stored in the SMEC. Information on this fault can be displayed to a technician by means of the instrument panel power loss (check engine) lamp, or by connecting a diagnostic read out tool and reading a numbered display code which directly relates to a specific fault.

It may be cheaper to go to the Dodge dealer and let them put it on a machine,I think they charge 75 bucks.
It's an 88 Thomas. Cycle the key 3 times. Pops the codes threw the engine light. $75 for a dealer...$200+ here in Indy.
