I have an 89 Dx hatch. This past weekend, we did the DPFI to MPFI and changed from OBO0 to OBD1 using a jumper harness and P28 auto converted to manual. The engine specs are B2 block, 2-layer Y8 HG, Z6 head/IM TB. It started right up first crank, idle perfect and then ran perfect for 2-3 days. Day 3-4, it began randomly sputtering, revs drop as if dying, then jumps back. It got worse very soon within 2 days and now it won't even idle. Try to start it, it dies right away. Itll idle high and then normal for about 2-5 minutes and then die. I read about the EACV causing symtoms like this, so we took it off, cleaned it and didnt do anything. Is there another sensor that could be causing this? MAP? TPS? We tried to drive it when it idles normal, but the slightest press of the throttle kills it. I hope you guys can help me out and sorry the post was so long.
