My problem was originally posted as cel code 15 but now it's a 5.

I replaced a connector for the positive wire coming from the ignitor and taped up a couple of the wires since they were frayed. I put it all back together, reset the ecu, and the same problem was happening.

It was still cold-idling at 1,000 really roughly like it was misfiring then shot up to 2,500rpm then died.

BUT this time instead of 15 the CEL code was 5 which is MAP sensor. WTF?!?! This car is driving me nuts.

Any ideas?

Here's my setup:
'89 CRX dx
'99 d16y8 vtec motor
'89 Integra ecu
Field's vtec controller

 

Check all the vacuum(sp) lines going into the Manifold(especially around the Map sens.) I got this code after I put on a new TPS and it turned out that I forgot to plug in a couple of vaccum(?) lines. Good luck.

 

It was a torn vacuum line. Thanks for the suggestions!
