rev then cut out?

[dubsport]

got the project up and running, bit lumpy but it hasnt been driven for about years. Think it needs a new manifold gasket as it sounds tho its blowing, problem is now if i rev the engine then stop the car cuts out 

the idle is hunting all the time usually below 1k revs ... also there is a weird high pitched noise then the oil, battery and temp (?) light flash and stay on ...

whats going on?

[rubjonny]

what car is it? if its a digi 8v classic symptom of a dodgy idle switch

[dubsport]

yeah its an 8v

just been out and changed the oil and the idle is now staying in one spot. what does the idle switch look like?

thanks for the help

[Jay]

yeah its an 8v

Digi or K-jet?


Search and yee shall find: 

its underneath the throttle body, cant really get to it without taking the inlet boot off!

ok now the temperature light just flashes and then when i rev the car the oil light flashes and a buzzer goes off  .. what the *£$& does that mean? 

[Jay]

Low oil pressure. Did you changed the oil filter when you changed the oil? Have you put too much oil in ? That causes low oil pressure too! Could also be a fooked sensor or oil pump 

How does it feel when you rev the engine up? Do the revs pick up quick?

[dubsport]

yeah changed the oil filter at the same time, the oil level is spot on.

when i rev the engine the revs do pick up quick but when i take off the accelerator the exhaust pops and it nearly cuts out then picks up again

Check out RubJohhny's tuning guide in the maintenance section  It's always a good place to start when looking at why they aren't running too well. I think it's the sensors if the oil level is spot on, *might* be the oil pump but I'm not sure how to tell if it's gone or not
