engine is fine in idle, as soon as i rev it up, it chokes and it goes dead
i'm getting these 2 CELs
- P0106 Manifold Absolute Pressure (MAP) Sensor Range/Performance Problem
- P1259 VTEC System Malfunction
here is the image of the manifold it that can help..


thx in advance

 

what's that Denso sensor that's just hanging out on top of the Intake Mani?

i'm not sure, it used to be on my b18c1 engine just bolted on the top of mani

 

I'd have to say that would be part of the problem, since it has 2 ports on it that nothing is attached to. it's just a matter of figuring out what it is.

Might have to look at a parts diagram online.

that hose from throttle body goes to one of those inputs on that sensor.. but i cant figure out where does the other one go.. seems like 18c engine doesnt have one of these.. so would it be worth replacing my manifold wiht my old one from 18c1?

 

does anyone have vaccum diagram for b18c? thanks

 

any input? please guys i need my car to work..

 

The map sensor is the one on top of your throttle body. It could be bad. Also make sure you don't have the tps and map sensor plugs switched as I hear this is a common mistake.

 

This is the vacuum diagram for a '94-'95 B18C1. Definately get those hoses hooked up correctly and all the sensors. The vacuum diagram should also be underneath your hood if the B18C was in your car originally.

 

that vaccum line u outlined in RED isnt suppose to be there. that piece of tube on have sitting on ur valve cover is suppose to go from the denso sensor on top of ur intake manifold (the sensor with 2 ports that arent hooked up) to that vaccum spot on ur manifold where u have that vaccum line that goes no where. also there should be another line coming off the same sensor into the (black can) on ur firewall

 

thanx for the help and diagram studs.. i appriciate that alot..

--- that hose thats on my valve cover is to big to fit the TB.. its way smaller then the size of that hose.. should i swap my TB back from b18c1 that's bigger?

thanx
