Alright so I ended up ordering an iac and tps from rock auto. I also got a leak down tester but haven't used it yet. After installing the iac and tps there were some changes. The explorer didn't want to cough out and die nearly as bad as it did before, which was kind of a symptom that appeared...

I forgot to post this but I ended up pulling out all the spark plugs again and making sure they were all torqued down to spec and in right after someone suggested that I couldn’t put them in too far or cross threaded them. I noticed this time that all the spark plugs in the driver side of the...

After some looking around I wonder if 543 is stored from when I unplugged the fuel pump relay to take a look at it when someone suggested it could be the problem.

I’m here looking at it right now and I checked the plug wires again and they all look good. The shaking has slowed down and it seems to be running much better than last week. I took it on a test drive but didn’t make it far when I started to get a popping sound in the front (right?) of the...

I'll triple check the plug wires again tomorrow. I'm using this diagram, it's right isn't it? It's the same I used when I replaced the wires I believe. How would you check if the throttle cable is stretched? And is there a way to tighten it? The light wasn't on last time I checked but I'll...

Update: I ended up deciding to do a compression test because I saw some things that said that might be the issue. I have the specific readings but it doesn't terribly matter because they all ended up from 100-120 psi which is above the recommended 100psi and within 75% of each other which I...

Update: I tested the maf wiring right outside the pcm and I was getting nearly identical numbers (maybe a tiny tiny bit smaller) to what I was getting by back probing the maf sensor. I also saw a video about listening to the fuel injectors to check if they’re firing, so i did that and they all...

Today I did a maf test on the sensor and got back numbers in what I think is the normal range. It has 12v power, is grounded, and the sensor return wire when idling (1000rpm) is 1.18v and steadily increases to about 2.2 at 4000rpm. I then took it for a test drive. It’s still bogged down super...

That's what I was thinking, I replaced the connector so maybe I need to look at the wiring. Does someone have a diagram or experience doing that? I haven't played with wiring much.

Good morning y’all, This is an update to the post from my brother's earlier post that is just above. Unfortunately, I must admit I have begun throwing parts at it as I know I very much shouldn't. Of course it hasn't fixed the issue so I'm back to the forums for some help. Quick background if...
