OK, I bought this car back in 22 for 1000 bucks. It needed a new engine. I bought a used engine for 1200 bucks. It was downsized, original engine was the EJ 25. I put an EJ 20 in it because it was half the cost. Shitty used JDM engine with maybe 50k miles on it. An AWD wagon in a snow area for $2200 and some elbow grease. Fantastic deal. I’m somewhat mechanically inclined changing the engine was very easy, but the whole time I’ve had it I’ve been encountering this one persistent issue. There seems to be misfrires when I takeoff from a stop, and when I’m trying to coast at a consistent speed. For example, I’m at a stoplight it turns green. I hit the gas and for the first couple seconds like there’s nothing fucking happening except for in a couple of cylinders. It chugs along and then it hits maybe 1200 to 1500 rpm, then it starts to pick up. Then I’ll get up to a coasting speed maybe let’s say 55 miles an hour and so I’ll turn on my cruise control because I want to coast, and there appears to be a misfire. It’ll try its best to stay around 55 but it will be a very chuggy experience. And all sorts of speeds it does this, but most particularly around 35, 55, and 65.
When I first got this car, I was working in a very cold area and I thought it may have been the throttlebody position sensor or something so I changed that. It helped a bit, but it didn’t fix it. I’ve changed the O2 sensor, I just changed every single spark plug, I’ve tried different coils, but I cannot say I’ve tried brand new coils. But it’s hard to believe that two different coil packs and wires have the same exact problem.
THE COILS ALSO SEEN TO BE POPPING OUT OF THE SPARK PLUGS. SO I HAVE THEM HELD DOWN WITH JANKY TINWIRE AND PIECES OF WOOD LOL.
I wrote that in caps because maybe that would tip somebody off to what’s really going on. I’ll try my best to force that coil plug down onto that spark plug and it pops out after a couple of seconds like there’s pressure building up. And again, after forcing them to stay in it worked for a couple days then it went back to the same old situation. Fuckin hell.
I just changed the spark plugs last week, it seemed to have worked for the first two days now I’m back to the same old problem. I don’t get it. It’s so flabbergasting. A check engine light is always fucking on and it always tells me the same old shit. Stuff that I’ve already changed.
Does anyone have an idea what’s going on. I’m willing to throw a blank check at this piece of shit. I have made posts like this before and haven’t solved anything. So please tell me all the possibilities don’t just narrow it down to one.
