Hey Roy, I have checked the belt on the alternator and it is pretty weak and bad like I see two tiny little tears on the belt. I also see small cracks on the belt and it feels loose not tight.

Replace it first and see if the issue still happens.

If you have a voltmeter check the voltage at the battery with the engine running. It should be 14 to 14.5 volts.

Okay will do and I do not, but I will ask a friend or do you know If any auto parts do it for free testing? I am going to charge it just it in case. Here is a first video. I have replaced the distributor and it turns on the first time and sometimes the second time now, but still sounds like idley.

So it starts when I crank it like the second time or third time and like the rpm arrow is good at first, but then when gets down to 0 or close to 0. Sounds like car is rigidly or like a shake for like three or four seconds and then runs fine. But, when I press the gas pedal lightly to see if it sounds like its about to turn off with that shake rigidly feeling and it does but when pressing all the way its fine. Just as I show on my video but when I start it again another time the car jerks. It is so annoying on every gear I shift like it is about to shut off while I am driving after every shift. I have new battery and distributor and code still shows the same of p1381. It is nerve wracking, lol. I really need help. :(

Before we say the PCM is bad lets check the wiring from the distributor to the PCM. Here is a guide to help us get started and the engine wiring diagrams so you can see how the system works. It sounds like you have one wire that is broken.

Check out the diagrams (below). Please let us know what happens.

Cheers, Ken

Actually I am 85% that I found out the cause. I need to replace my gaskets on the valve so I got the valve cover gasket kit because there was a lot of oil in the spark plugs so changing them as well. After that I am going to do a compression test. If the cylinder head is good or at least one cylinder misfire so I can use the product Restore for compression and if more than two cylinder then I am getting a new cylinder head. I have checked the wiring from distributor to the ECM looks fine, but since you said one wire I am definitely going to check it again with the test you showed me and thank you for that. Truly, because it is a drag getting this baby back on the road. But I will check the wiring test that you show me, but I think it is the PCM because the cover is rusted bad but still some metal around. It looks like it have been humid like it has been in a sauna because I see water like a water bottle spray been sprayed all over the cover even in the inside cover housing of the PCM. I am going to take out the cover to check the PCM/ECM tomorrow or this night hopefully, because I am thinking it got corroded or humid water must be worn it out or something. I hope it is only one more again thank you so much so, so much. Having my fingers crossed. :))))

Yep, any moisture will cause the issue. Let us know what happens and please upload pictures or videos of the problem.

So, I am confused. I looked in under the ashtray that ob2 plug for the scan tool and follow the wires to the ECM/PCM also the wires from the distributor to the ECM/PCM they look fine. I did not want to take the plastic black stuff off because the wires look too good to me. But I want to be sure I am not holding the TCM because I could not find another computer on the other side or in the middle of the radio but on the passenger side under the feet cover. It was only one computer with three connections and I want to make sure if that is the ECM/PCM not the TCM on my car. But, yea I see that there is small corrosion. I am going to post a video and pictures of the computer. It is a 1996 computer it shows the date.

I will upload the video tomorrow. But I have seen the ECM and as you can see the joints are corroded for such an old computer. I do not know if you can see that but the joints are like yellow and at first I thought it was normal copper joints, but it was not it was brown yellowish corrosion around all joints and its small brownish spots on corners of the plate chip itself on the back side. The picture shows the front.

Yep, that does not look good. Can you smell a burnt electrical odor? If so I would get a used PCM and plug it in to see what happens. These computer sit low in the car and are subject to moisture.

Okay, will do and no but it did smell like an odor of like a weird moisture metal smell a little but definitely smell moisture right after I pull out the rug and see the cover. But yes I am going to wait until Friday (payday) to get the computer. And do my valve cover gasket kit and check my cylinders with a compression test. Hopefully they are good if not that is not good. Going to have to get a cylinder head and go to a real mechanic shop. So they can save the timing when they install it because I do not know how to do that. Haha. But hopefully again they are good. Thanks for everything Roy and Ken you guys are very very helpful, I thank you a lot. :))))

Hello I am back and still have problems. :/ So I have changed the valve cover gasket with the kit and new spark plugs got a computer from the junkyard and tested two of them from the old and from the junkyard and same problems. Cranks but it does not start. I bought a new distributor with OEM parts online at RockAuto and my model is a DX engine is f22b2 just throwing it out there. Because I found out that is my model of my car, but still it sounds like the distributor or the connectors or like you said the wire with the connectors of the distributor that a wire might be broken. :/ How do I test that when I find the wire?

Thanks for the video it sounds like you have love compression in one or more cylinders. Does the engine have spark? If so will it run on starting fluid?
