Alright it is the last thing to try that seem like it may work... I went to do it today but I have to much fuel in the tank... it looked like if I opened it up it would spill all over the place... I think I need to get the tank down to 3/4 or less... before I can open it up ...After watching the video my money is on the fuel pump.
When you depress the accelerator abruptly and the throttle opens quickly you'll get a large volume of air flowing past the throttle body and into the manifold. On a carburetor there is a mechanism called an accelerator pump that squirts fuel into the throat of the carb to address the sudden rush of air. On a fuel injected car there is a similar function in the software that delivers a bangshot of fuel when the throttle is opened quickly. If you have a fuel delivery problem you will get exactly the kind of symptom you are feeling when you quickly accelerate from a idle or low engine speeds. When you accelerate very gradually there isn't a huge rush of air that requires immediate fueling which is probably why the car feels fine when you are gentle on the accelerator.
Also, since the car is taking longer to start when it's hot that suggests that the fuel pump is failing. As a matter of eliminating the most likely problem you should put the stock fuel pump back in and bypass the boost-a-pump. I am almost certain this will solve your problem provided your stock fuel pump is still functioning normally.
Glad you were able to solve the problem. It’s unfortunate that you spent good money for a subpar job. Definitely have a word with the installer.FIXED! Now who gets the $50? A few of you pointed at the fuel pump... The car feels great! I would really like to thank everyone that took the time to help me out with this!
Looks like it might be @sigintel who first said to pull the booster and pump. Go back to stock pump.FIXED! Now who gets the $50? A few of you pointed at the fuel pump... The car feels great! I would really like to thank everyone that took the time to help me out with this!
If you don’t want it I will donate 100 to St. Jude’s children hospital... PM me if you change your mind... Thank you !Pay it forward back to the community?
Someone will need your help one day.
Think Op actually had it in his data.
Because the fuel rail does not feed both sides evenly, when flow is corrupted with fuel vapor (stalled bypass type pump) or pressure drops, the differential short term fuel trim bank to bank comparison may show this non linear “flow load” vs “pressure” response.
Wow!If you don’t want it I will donate 100 to St. Jude’s children hospital... PM me if you change your mind... Thank you !
