Ive got a 88' with street ported engine just rebuilt but runs rich, any help?

 

You need to post alot more to get a good answer, Mods, Intake, Exhuast, ect?

 

Its got cold are, dual cat backs, bigger throttle body and some ceramic parts in the motor...

i dont know too much about rotary's, im still learning =(

 

What does a high idle have to do with running rich? Not at all the same thing. When does it run rich, and how do you know this? The stock fuel maps are rich to begin with.

 

Bigger throttle body? Ceramic parts?

There is really no way to make a bigger throttle body without major intake work. So if you could post details on this, that would help greatly. My guess is that someone ported out the throttle body and then did not reassemble or adjust it properly.

It could also be due to a vacuum leak (or several).

 

yeah idk what the guy did i do know its street ported, and its running rich cuz you can smell it and it back fires, also it has high idle when it turns on which idle is supposed to be 750 i think and its idling at like 1500-2000 so yeah....


and the ceramic parts ill get back to you on i have to call the guy...

 

Did you adjust your TPS? I dont know if that could cause high idle, but I know it will cause it to run rich.

The high idle may be due to a vacum leak.

Do you mean ceramic apex seals?

 

yes! thats it, ceramic apex seals.... yeah i do know i have a small oil pan leak, im still waiting on my mechanic to get back from vacation and thanks for the tip guys ill mention everything to my mechanic!

 

ceramic seals?? u may be in trouble...

 

The car is supposed to idle at around 1500 when cold.
