I have a 93 del sol with a d16z6 swap rebuilt with 15xxx miles
New catalytic converter
New 02 sensor
New spark plug
Spark plug wire
Cap and rotor
I just passed smog

My problem is my car Boggs random while I drive

No check engine code

I got the car bone stock d15b7 and it Boggs also
so I swap a d16z6 and replaced a lot of stuff

I can't figure why the car Boggs

The d16z6 was in my other car and ran with no problem before I did the swap

Check the TPS and possibly the fuel pump or the fuel pump relay

My tps is fine I had this whole swap in my other car and it ran perfect I did the swap because i was thinking it would help

And change my main relay with 3 different working relay

How do I test my fuel pump?

Don't just say "it's fine", test and re-calibrate it.

check the fuel pump sediment screen
