Car bogs down, wont accelerate Sign In

2000 nissan altima, GXE

Hello, I have been having some car trouble and I cant seem to figure out what is going on. I've been given multiple suggestions and tried a few things and am really feeling hopeless and unsure what to do next. There were a series of events that happened specifically so I'll try my best to get them in order.

I've had an oil leak for some time, nothing thats been alarming though. I checked my oil level about a month ago because my car was sounding loud, and the level was empty, I was out of oil. I drove to a gas station a quarter of a mile away, put a quart in, and then drove home roughly fourty miles. Because at the time my understanding of engines was, lets say insufficient, I added an additional five quarts of oil the same day because I got home and the level was empty which seemed odd. I thought everything was okay, and the car was driving fine.

A few days later, I thought I could improve my engine because I had been told by an old mechanic I had a minor head gasket leak, and since I knew I was leaking oil I thought I'd "fix" that too. I bought some stop oil leak from walmart, as well as head gasket fix.

I poured the head gasket fix into the radiator, which didn't do anything besides clog it up, and the stop leak into the engine. This where I am confused as to what could have caused my current engine trouble, was it the fact that I drove with no oil, overfilled my engine with oil, or that I added something to the engine within in such a short period of time that clogged God knows what.

After I added these items my car ran fine for about three days, and then I'm driving on the highway and the performance immediately changes; the car won't accelerate higher than 30mph, when I give it gas it will rev up high without accelerating, or bog down. I pulled over and my engine oil level was very high. I managed to make it home and have been trying to figure out whats wrong since.

First thing I did was drain out all the oil, and put in the correct amount (about 3 1/2 quarts). I checked my spark plugs, and until a couple days ago they were all white recently they were black before I did the cylinder pressure check: I measured the pressure in my cylinders and three of them were at 150, while one cylinder was at 130psi. I checked my MAF sensor and that seemed to be okay I got power from it by using a voltage meter. I looked for obvious cracks in any hosing around the engine. I managed to take the car to oreillys and the electronic diagnosis gave me one code, P0455 "Evaporative Emission System Leak Detected (Gross Leak / No Flow)." I added sufficient gas in my car, the cap was on tight. They told me to check the PCV, which I have not done yet, and I've also been told to possibly check the fuel filter.

I recorded a short video of what happens because this might be easier to understand what's going on. Going to a mechanic is a last resort at this point because financially it is draining and not something I can easily afford. If anyone has any suggestions or could help I would greatly appreciate it, thanks.

Might want to take that thing into a local reputable professional repair shop. Someone is going to need to look at some data stream information, perform diagnostics, and find out what all that noise is.

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

IDK on this one DS. May just weight it and see what the metal is worth too. This sounds pretty messed up already,
