I need help ive tried so many things my b18c is lagging and it annoys me i did a rebuild on the head and new postin rings and all seals changed the dizzy and spark plug wires and spark plugs ive changed the ecu and it still wont go away i have no clue what it is and for some reason im getting some gas in my oil please help!!!

 

Check compression tell us the numbers also is the check engine light on?

 

What are these things you've tried so far?

 

Compressions are fine my mechanic checked them for me and check engine light will come on sometimes

 

New dizzy . new spark plug wires. New spark plugs . diffent ecu . complete rebuold of the head and has new piston ring

 

Did you change the distributor after the build or was that done in conjunction with? Check your mechanical timing. Can you describe the lagging? Is it at certain RPM's? All the time? Is it a bog?

 

I changed it before but its brand new and yea its a lag and it bogs out in 1st alot and wont catch speed quick and rpms drop lower then 1k sometimes

 

Check the code, if it runs fine then bogs on and off and doesn't accelerate it could be the primary O2 sensor but first check the code when it comes on. Don't just buy one and spend $60.

Still I don't see how you can get gas in your oil and have perfect compression? It has to be leaking somewhere in the head gasket or piston rings.

Let us know the Ecu code

 

Yea ill check the code once i get a chance and yea never changed the 02 sensor so maybe and yea you dont think it could be my injectors feeding to much gas ?

 

check that your tps and map sensor arent switched?
