Guys,

I took out my 240CC jdm SIRG injectors and used 290CC jdm ITR ones.Car drove good for 10 days, untill last night>

Car was responding fine,does not drive that good as OEM 240CC ones, untill lastnght, Air/fuel ratio only in LEAN at full trottle, car drives less in perfomance.

I had some of 2000 Si (240CC) switched > outcome still the same, LEAN and little response.

I thought it was Mybe> Fuel pump, so I cheked ECU codes, no lights show up blinking etc.

I switched back to my 240CC jdm SIRG ones, and car response much better as before, in STOICH/RICH section A/F etc and good response.

My Q> does this has to do with Impendance of Injectors (ohm) ?

regards,

Rishi

 

did you get the injectors new? it sounds ask if one of the injectors isnt pulsing fuel into the chamber corrrectly. check the injector for leaks. check the small o-rings and the seals.

 

Ok, I will chek them out

the ones 290cc were flushed/calibrated before I put them in, but it seems now that one or so was leaking.
They were not new, bought them from someone on HT like 8months ago, and put them in like last week.

appreciate the help.
