sometimes when i go to start my car it will start up and idle perfectly fine .. but then other times ill go to start it and it will start but have a terribly bad idle for about 30 sec than catch the idle back up to speed .. kinda like its choked out of gas .. when it idles like this the car shakes real hard .. hard to explain but the car putts sometimes when starting .. i dont see how this could be a fuel problem unless its the pump itself .. i run premium gas everytime since i had engine work done about a month ago

 

Is there by any chance you tune the car by yourself by using aftermarket engine management like HONDATA, Chrome, etc

 

F-***... i got an ecu from the internet .. that was tuned to my engine but it wasnt a dyno or anything .. u think it could be tuned wrong .. maybe for bigger injectors

 

check iavc

 

"The internet" is very vague. Where specifically did you buy it? Yes, if it's running a custom tune, that might be your problem.

 

Probably Ebay or Craigslist. Did it run with the stock ECU?

 

EBay .. its a chipped p28 .. obd1. Yeah its pretty vague but I told the guy exactly what I was running .. aNd no it has a jumper harness on it

 

Try to run it with stock ecu first and see how it goes.
