running rich need help

[95exb18]

i have a 95 ex with a b18a swap in it and it is running really rich and when i push the gas too hard it keeps bogging down, i have a completely stock motor with basic add ons like intake and header what could be the cause? anything will help me out right now. thanks

ECU, Timing, TB, anything to do with fuel sending

Sometimes its just as simple as making sure your air filter isnt clogged, it may appear clean but those particles are small and sometimes undetectable.....take the filter off your intake and see what happens, if it improves its your filter if not then we know the problem is else where....i would try that first before you go mess with timing and ecu

Is this a new swap, or have these problems recently started?? Tell us more about what all was changed with the swap...Any CEL codes??

its not a brand new swap its like a year old, and it just statred a little bit ago, it runs fine sometimes but then for like 5 minutes at a time it will run really rich. no codes at all

Just had this same exact problem. my tps and map sensor were backwards. try that. and clean your spark plugs after. they will be comletely blacked out.

alright man, thanks a lot, ill give this a try and let you know what happens

 

[95exb18]

alright so i just went and popped the hood after a little stroll and i see that there is oil leakng out of where the throttle body and intake manifold connect, what would cause this? and is that something to do with why it runs shitty?

 

[TigBitties]

im pretty confindent it has something to do with why its running so shitty. they shouldnt be leaking anything, but i have no idea why this is happening.

 

[93Civicspeed]

That might be the OilPressure sending unit as well cuz thats about where that is no?

 

[TigBitties]

well if there is a leak around the throttle body. it should be running like there was a vaccum link i think? anybody else know? Is there a hose running from your valve cover to your intake?

 

[93Civicspeed]

PCV valve I think but Im not sure

change your primary o2 sensor

 

[95exb18]

change your primary o2 sensor

02 sensor is under a year old,

Does the CEL work?

Is the engine running cold?

Do you have an exhaust leak?

Have you inspected the plugs, wires, cap, and rotor? Is the ignition timing set to spec?

 

[TigBitties]

lol havent heard RonJ say much lately. welcome back sir

it does have a exhaust leak. i think the cel works, not sure tho .... oh and it doesnt run cold it heats up fast but doesnt over heat

Where is the exhaust leak relative to the primary O2 sensor?

If there are no codes thrown, the CEL should turn on and then off after 2 seconds when the key is turned to ON(II).

theres a leak by the cat and then right by the muffler where i ran out of rod for my welder. and i noticed when i let it warm up and idle it shoots gas right out the exhaust only when its warm tho
