well ik when i got the car it would idle down and die the first start or 2nd.But now im having a issue where car will pull to 5,500 and acts like a 2step same as when its in park i can undo battery cable and reset it bamm its back to normal.Now i got vtec to working atleast i think its not throwing a code for it anymore.Ive also read the faq about the iacv but its more like a hard miss and dies.Another thing is car want throw check engine light codes unless the car is running never had this issue out of any other hondas and its throwing code 41 which is the 02 sensor.Was told my ecu could be bad?Also prev owner took the fuse diagram sticker out from under the engine fuse box can anyone show me those fuse digrams?Also have a d4 light blinking where is the cel jumper for the TCU?Ik lots of question just trying to get her right to decied if i want to keep her or not.Its a 92 accord dx auto f22b1 running a
p0a ecu.

CEL connector for the TCU should be right next to the one for the PGM-FI ECU.

It would help if you told us what you/previous owner swapped into the car. Because none of the CB7 accords had a Vtec motor in them from the factory.

Says at the bottom what swaps in it which is a f22b1.And what color is the jumper for the TCU?

F22B1, that motor came out of a CD5. So you could be into a whole can of worms there if they didn't do the wiring right.

the TCU jumper and ECU jumper plugs should be blue.

If it's going back to normal I would say your ecu is suspect for sure. check the electrical connections to your o2 sensor as well.

Well im pretty sure its running the stock dx harness only thing diffrent is i pined for vtec.Car runs amazing for a big auto boat when it runs right.But sense i dont have the fuse diagrams for the under the hood fuse box idk which fuse is for the ecu to correctly reset it ik its a 7.5 fuse correct?and anyway to reset the TCU aswell?
