Hi Tracy. Welcome to the D. You have to add punctuation. Most people here will not read a post that is a run on sentence/paragraph.

Now you say you have a p20 trans, are you a manual gearbox?

Also is it a B000 or an A000? It is stamped on the housing just above the passenger side axle.

Hey thank you for your reply, sorry about the punctuation. It is a Manual gearbox, and please bare with me as I am going to check the passenger side above the axel. Thank you again

Ok so it sounds to me like you have an auto ECU installed. The code 19 applies to autobox only. Change you ECU out with a manual ECU, and I bet your problem will be solved. GLOP

Hello again just swapped out the ecu, still engine in limp mode but now no codes flash out, engine light srs light and brake like light up when cars running. I put in the old ecu and it was still the same code 19. Also I noticed the cat is glowing red after running the but it don't seem like the engine is missing.

If it's glowing, it's either clogged, or running rich, and the fuel is burning inside.

You may need to check your engine code, and make sure it matches the head, because if someone dropped a mini me in there and didn't tune it, you could have some serious problems on your hands.

I had got it from a friend and it use to run I saw him drive it daily and then he let it sit and sold it to me. He had let it sit for about a year, before letting it sit he drained the fuel so the fuel didn't stay in there and all we did was put gas in it, then it started with code 19 limp mode. That's why I am very confused on what is wrong with it, because of the fact he's a good friend and it ran before he drained the gas and let it sit.

Then something took a crap in that year of non use, or he stopped running it because of that problem, and didn't tell you.

Ive had a glowing cat from a cracked valve. Do a compression test on the car. The code 19 shouldnt affect drive-ability at all. In fact if you google search you should be able to find how to convert a auto ecu to a manual. Just have to remove a resistor.

I was there when he parked it then then next day draining the fuel. Still confused on what has happened but I did see something about converting a automatic ecu to be use with manual. if it is a auto ecu, why would it be running a year earlier then not run right and throw code 19 confusing to me :\

Its not the ecu. Do a compression check and report back. Dont post until you have the numbers.

Are you reading the code right? What's the code on the side of the ecu case?

Are you sure you have the proper ecu/head/distributor on the motor?

I have tested the distributer with my power probe and found it was bad. I had went the to junk yard and got parts off d15b7 thinking it's the same thing, meaning I got the manual ecu from it to test and the distributer, idk if the Parts could be doing it I just thought a d15b is a d15b and the parts should be able to be used, I am doing a compression test today and will get back with you on the numbers. Thank you all for your time and advice, I usually work on diesels which is why I am not all to familiar with this so thanks for your patients.

I believe it is the d15b vtec not the 3 stage, so if it is japan market only where am I to find the right parts or what motor can I cross parts over from?

Yeah, you can't use a b7 ecu on that motor. The b7 is a non vtec motor, so you won't ever get it to run right on that. I'm not familiar with the d15b's, so I couldn't tell you what will and will not work, but from what I understand, it uses many of the same parts as certain USDM motors.

Swapped new distributer motor runs ok, no limp mode and the cat is now not glowing red. Tho the cel srs and brake light still stay light up, but the ecu from the d15b7 seems to make it run better then the auto ecu that came out of it.
