Okay so I did a DPFI to MPFI swap and my engine is like constantly bogging and sound like a lawn mower, it feels like it has a crazy misfire but I don’t know what it would be, I have good timing, compression, and the injectors are working. I’m getting cel codes 10 and 14, I don’t know what to do and I can’t for the life of me getting it running right

 

First check 10 and 14.

I believe 14 is the IACV

Check that the map tps and iacv are hooked up correctly.

 

I got rid of the 14 code and now it’s just the 10, car won’t idle now starts then dies unless I gas it and when I do gas it, it sounds like a lawn mower so I’m assuming it’s running on 3-2 cylinders, my injectors are good, my wiring is good, spark is good, TPS is correct, MAPS is correct, IACV is good and plugged in correctly, but it just sounds horrible and the timing is correct but i just don’t know what it could be

 

You’re 100% sure the TPS is calibrated correct?

You’re sure the spark plugs are in the correct firing order?

code 10 is your IAT.

 

I think my TPS is fine it’s .5v at idle and 4.95v at full throttle, my firing order from the distributor is correct from looking at a d16 of a working delsol, I feel like the IAT wouldn’t be causing the problems I’m having right now the car isn’t bogging much anymore just refuses to keep idle and sounds like it’s not firing right and I know the timing is good so I’m just confused
