Alright so I got the swap in and when I went to run the car, it ran like this. You may have to turn the speakers up, its not the best quality, but let me know if this tells you anything. I can rev and keep the car running as long as I do, but the car sounds rough, and without rev'n it will just stall out.

 

Did the CEL remain on? If so, pull the CEL codes -- see CEL sticky at the top.

What car, ECU, and engine harness?

 

The car is a 98 civic DX stock harness with an OBD1 converted ECU tuned for this engine

 

Any CEL codes?

 

I'll have to read that and run it. I was just seeing if anyone recognized the issue easily.

 

Had someone on another forums tell me its probably just the tps and map sensors reversed, so I'll check that first I guess.

 

Post the wire colors for each connector.


And avoid guessing --> Pull the CEL codes first.

 

Ok so the car threw 10 and 21. Both of which would make sense I guess. I don't have vtec wired in yet, and I can imagine the TPS would throw if the two were switched, but I don't get why it didn't throw a code for the MAP

 

Nevermind, 10 is intake air temperature sensor. I have that connected, but just pretty much sitting there. Its not in track of my intake. You think that alone would make the car run that rough?

 

Everything I'm reading about the code leads me to think that the car would still run fine with it throwing that code. So I don't think thats whats making the car run like that.

 

Post the wire colors for the TPS and MAP sensor. Swapping connectors does not always throw CEL codes.

Is the IAT sensor plugged in? What color wires are in its connector?

Also check the plugs, wires, cap, and rotor.

Did you already check the mechanical timing?

 

Sounds like a vacuum leak. possibly the vacuum line from the intake manifold to the brake booster.

 

yellow/red, green/white and green/red for the TPS plug.
yellow/blue, green/black, and red/black for the MAP

The timing, rotor, plugs, wires and caps are good though.

For the IAT, those wires colors are, black/blue, orange, and yellow or white with black.

 

Your TPS and MAP sensor connectors are indeed swapped.

 

This is the IACV connector not the IAT connector.

 

For what its worth, it seems like the TPS and MAP couldn't swap. The way its loomed, its real close with the injector plugs and stuff. Is it normal to have to maybe cut back the looming to make it reach

 

The wire colors in the connectors definitively say that your MAP sensor and TPS connectors are switched.

And the three wire IAT connector is actually the IACV connector. The IAT sensor connector only has two wires.

 

I guess I'll have to cut back the loom then.

 

I'll keep it updated once I try swapping the tps and map. I don't think it is any vacuum leak however

 

Tps and map switched...video coming up
