The best showing off to find a leak is to have the engine doling out and warm and after that spray can lighter gas /propane or brake cleaner a propos each joint in turn. If the engine rev s in the works you ve found your leak.
Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me say you a little more about the misery history.

Hello the TPS does have an effect on switching the car into idle mode in view of that I'd recommend to make distinct the throttle plate is 100% closed and not slightly high and dry in the manner of carbon. and subsequently become accustomed the TPS in view of that that the IDL attach is continuous to the E2 stick bearing in mind the throttle is closed, and right to use circuit taking into consideration the throttle is just cracked. Don't worry not quite any voltages, the IDL entrance is the in reality important one.
