Back when my car started having problems I changed out the map sensor, plugs, distributor, and the close code came on and I fixed that and now it's throwing a code 7,8 at me now. Tdc and tps. What would cause this? First code 4 and now code 7,8 and since the ckp it's been in limp mode and hasn't been driven.

Car information is required for all tech threads.

After you post that, ohm test the distributor sensor circuits from the ECU connector.

I will check it in the morning.

I have a 96 civic. B18 board to b20 2.0 with a type r head. I replaced the dizzy from code 4 and it have me the same code so I check the connections and the code 4 went away. I thought I had it then it through code 7and 8.

b18 board? what ecu code is on the metal casing?

Did you check to see if your tps is properly adjusted?

Does this car have a hackjob engine harness?

Yes it's a ls/vtech. 2.0l instead of a 1.8.
The ecu is a hondata. P28
The harness is done right. My buddy who was a tech for many years did that.

Double check what ecu is needed for B series. Pretty sure its not a P28 but P75

Come back after you've done this^

Post the Ohm readings.

P28 works for vtech. Which it's running.
