Honda-Tech - Honda Forum Discussion - TPS and MAP codes need help

Hello all, new to the forum although I've been browsing for awhile. Long story so bear with me.

Recently purchased a 93 civic coupe DX (1.6 vtec swapped) from my brother to use as a daily beater to get miles off my current car. He owned the car for 12 years with relatively few issues. The car has been sitting about a year when i decided to pick it up. I put fresh gas, changed the oil and did a few minor things to get it road ready. The car ran flawless for about 200 miles. I was driving to work and the car lost power, CEL came on, I was pushing the throttle but nothing was happening, then it died. I coasted to the side of the road and tried to restart, would run but when I gave it gas it would shut back off. After about 10 minutes it started up and ran fine the rest of the way to work. I went out at lunch and tried to start it but it would run for a split second and then die. Checked codes, had codes for MAP sensor, TPS and vtec (VTEC is not a concern, my brother says that would randomly come on and go off, thinks it is a wiring issue, and I don't drive the car hard so I do not care if VTEC works or not).

I unplugged the TPS and it would start and run, plug TPS in while running it would continue to run, only if I tried to start with TPS plugged in it would shut off. MAP sensor made no difference on running or not. I did not attempt to drive the car at this point. Few days later (TPS plugged in) I swapped the map sensor with a known good part and the cleared the codes. Car started up and ran, no CEL. Swapped back to my old MAP and same thing, run and no CEL. So ok at this point I drive the car with the old MAP sensor, TPS plugged in, basically how it was when it started having the issue. Ran fine, did a short trip and ran it hard into VTEC, VTEC worked, a few miles on while driving hard the CEL came back on. Car continued to run fine, checked the codes, all codes returned. TPS, MAP and VTEC. Using a multimeter I checked voltage on the TPS and checks out within spec. (.48 at idle, 4.4 WOT if I recall correctly)

So at this point the car seems to run ok, however with a check engine light. I'm reluctant to drive it home from work yet because I drive through a long section of 2 lane construction with no emergency pull offs. So I would hate for it to break down there. I'm kind of at a loss as to what could be causing the issue. Next step is to swap the MAP sensor again and drive the car to see if codes return. Any ideas? Thanks for any help!
