Engine has low power?

Wet spark plugs indicates that the sparks are either weak or non-existent -or- less likely too much fuel is being injected into the engine. I'd go get a spark tester (maybe $15.00 to $20.00 at the auto parts shops) and check for sparks.

Here's the tester that I use. It's pretty simple. https://www.amazon.com/Lisle-20610-Inline-Spark-Tester/dp/B0002STSC6/ref=sr_1_3?ie=UTF8&qid=1501325755&sr=8-3&keywords=spark+tester

Basically, you pull the plug wire off of the ignition coil (also pictured below) and plug in this tester between the coil and the plug wire. Then get someone to turn the key while you observe it. If it flashes, then you have spark. Check all of the cylinders.

If you have good consistent spark at each cylinder, then the next thing I'd look at is the plugs and wires themselves. Incorrect plugs and/or wires, or really worn out plugs and wires will keep the car from running well, if at all. This guide doesn't completely apply, but if you scroll down you can see information about inspecting the plugs. Here: https://www.2carpros.com/articles/how-to-change-spark-plugs

Start there and let me know what you find. We'll get your car going again.

Hmm, is the service engine/check engine light on? If so, get it scanned and let me know what the codes are. An issue like this could be a lot of things. Most of them are spark or timing related. I'd probably suspect a failed camshaft or crankshaft position sensor.

I'd like to have the VIN so I can see exactly which engine you have. My information shows three different 1.6L engines, probably with only minor differences. Again, if the service engine light is on, get it scanned and post those code numbers on here.

Hello,

It sounds like you may have a catalytic converter that is fallen apart and blocking the exhaust at times. Here is a guide to help confirm the issue:

Please run down this guide and report back.

That does sound like a possibility. Good thinking, Ken! A definite possibility at 160,000 miles.

Yes, the catalytic converter sounds clogged, how did the test turn out from the guide above?

The catalytic converter sounds good. can we check the timing belt timing it could have jumped a tooth? here is a guide:

Please let us know what you find.

Can you please shoot a quick video with your phone so we what the car is doing? That would be great. You can upload it here with your response. Does the transmission cause the issue or the engine?

Please do.

Fuel pressure can cause the low power issue, also ignition timing. Does it have new fuel filter? Can you please check the ignition timing? The video will help. :)

Sounds good.
