New to the forum having a problem with my cb7 it has and h23 dohc and I cannot drive it unless the engine is warm when its cold its like riding with someone who can't drive a stick it jerks and hesitates. When its warm I'll come to a stop and the rpms will drop almost to the point where it stalls. Can anyone point me in the right direction

 

Any codes present? When did you tune-up last?

 

Either a tune up or a serious vacuum leak.

 

When I experienced that problem, i did a complete tune-up, seafoam, changed all vacuum lines, cleaned erg and pcv valves, and she purred like a charm. Hope that helps.

 

No codes pop up just did a tune up. But ill check the vac lines. It also has an a crack in the exhaust. Gonna seafoam it today thanks for the help

 

That's not an issue at all...

 

I changed out all my vacuum lines as well, it help but nothing like calibrating the engine though

 

I can't even understand what you're saying. First you say it's having problems driving when it's cold, then you say you have problems driving when it's warm.

 

FITV/IACV issues? I also am having difficulty in understanding exactly what the symptoms of your problem are.

 

Not running a fitv and brand new iacv . The car will not go above 3k or it pops and sputters until it gets warm. And when its warm if I stop at a light its like it wants to stall goin from about 750 to about 450 then just goes right back to 750. And I apologize if it sounds retarded but the symptoms I'm having I've never seen before and none of my friends have ever seen.

 

If I didn't know any better I would say you're running the wrong injectors.
