need help with b16a stock with stock p28 ecu starts crappy when its cold have to crank it like 2-3 times before it starts .while driving if i hold the gas down 1\4 it picks up ok but wen u floor it at about 3000k rpm it bogs out like crazy

 

Try running a stock p30 or a chipped p28 and see if it still does the same thing. it sounds like its leaning itself out.

 

I had a stock p30 did the same thing

 

is the car throwing any codes??

 

Idk check engine off its obo jumped to obd1

 

Thread titles MUST summarize the tech problem so that members browsing titles can easily understand the problem without reading the post -- Title edited.

...and...

In your first post, you MUST provide all pertinent information about your car and engine. Failure to do so may result in thread closure.

 

Have you checked the timing?

 

ECT sensor is most likely your issue. only starts quick when car is warm rite?

 

Check your compression. Bad compression will do this

 

Timings good
Ill.check the sensor and compression
