Fuel Problem

[jmcleavy]

Sorry stamford, I'm trying to find out stuff for you but only got my phone to post replys so its a bit of a nightmare fella!

[stamford]

Okay, don't worry too much, every snippet of info will help. We'll get there eventually.

[jmcleavy]

Cheers fella

Right, just talked to the guy, he says pressure sensor inside the inlet manifold has failed, can't get to it because the manifold has been plastc welded to fix a previous crack. That's the story guys, over to you

[stamford]

There isn't one inside! All sensors and vis units are external and accessable. That is the only plastic component that fits the description. Correct me if I am wrong here guys but the only parts connected to the plenum are:

• Power vis unit-screwed in.
• Balance vis unit-screwed in.
• MAF sensor-screwed in.
• Purge valve-screwed in.
• Then throttle body with potentiometer and IAC valve screwed in place.
• Other than that its push fit breather piping.

As for pressure sensor, lost me there bud unless it is the MAF sensor? But that's external.

[jmcleavy]

Wow, now I'm completely lost

[jmcleavy]

IIs there anything else that qould make it lose vaccum?

[stamford]

Is the diagnosis correct? Has the car been plugged into a diagnostic reader?

[jmcleavy]

I plugged one in and it came up with no error codes. i think these guys are guessing to be honest.

To recap, car would rev and cough, when you put foot on pedal it would cut out. all plugs been changed and is better but still coughs, like there is air getting in
