To summarize the situation. I just recently rebuilt my cylinder head on my 98 Prelude. Now that everything is back together, the car starts but once it warms up the engine does not want to idle and dies.

The ECU throws 3 codes

13 Barometric Pressure Circuit
14 Idle Control System Malfunction
Idle Air Control Valve Circuit Failure
17 Vehicle Speed Circuit Malfunction

This is a previous post I made regarding this problem.

I ended up replacing the IAC and the MAP sensor with a good condition working one and it still does the same thing.

I know I got the timing on correctly. It's not the timing.

So im trying to figure out what else could cause this?

 

do you have a helms manual?

 

Yes I do.

 

sweet.
take the codes you pulled and go through the troubleshooting for each one. If you need help hollaa
