I've been having troubles with my 1jz at low rpm, feeling like it could be the fuel pump.. it feels 'chuggy' at the start. This happens in first gear mainly and mostly when the car has been drivin for about 15mins. (after its warm)
I also had it looked at and our thoughts were still the fuel pump. I did replace the pump with the Walbro 255. I could feel the difference in the type of pull with the new fuel pump. The last one would punch it to 12psi and id be hitting fuel cut at 4000rpm.
After 15 mins of driving not too agressive, timers only at 1.00, I am still getting the chuggy starts!
Can anyone help me?
Thanks Alot!
