Ok guy my problem is that I make the car front dpfi to mpfi and the car start good the first time I but the key in on but don't wanna rep night then 3,200 I check all the wiring and everything look good I put the e u in my other car and work good to the motor is a d16z6 with stock p28

Sorry for my English guy

I use this to convert he car to mpfi

Here is the video of the code the car is conver to obd1

 

I got 7,10,14. Out of that. Research those obd1 codes and fix them to get rid of the check engine light

 

That first code 7 is for your TPS(throttle position sensor). That code for sure will def cause those problems because I just went through this issue with my TPS. Get a multimeter and check for voltage at the middle wire on your TPS. Get the voltage for the throttle closed and then at Wide Open Throttle. I think it should be around 0.5 closed and around 4.5 at WOT. Code 10 is Intake Air Temp which I doubt is causing you these problems. Code 14 is IACV.

 

Thank u guy I have longer video guy are u think there is more code

 

And what u gy up think about the dpfi to mpfi conversion in the ling is good guy bec I switch the tps wire like the ling say

 

Make sure you put the connectors on the correct sensors.
Some of them look exactly the same and accidentally get put on the wrong sensor.

 

I have the tps and the map sensor good and the other 2 in the other side of the intake are good 2

 

Hey guy I check everything and still have the same problem

 

So you probed the TPS with a multimeter at idle and at Wide Open Throttle? What was the voltage for each?

 

I but the key in on and read front yellow to green 4.99 yellow to red 2.88 red to green 0 that how u read

 

Put the key in the on position. Probe the middle wire. Should be around 0.5volts. Now, have someone hold it at WOT and probe that same middle wire and it should be around 4.5 to 5 volts. Try that and report back.

 

Ok I put the key in on engine off and the tps sensor was plug and I read .53 in WOT 4.46

 

What the voltage I read mean is good or bad

 

Help I don't know what can be people help please

 

that should be close enough to the proper values to not make a difference.

 

I was thinking in the crank shaf position sensor what u guy think
