High Idle

[heinz]

The 2E engine in my mk2 idles at 1200rpm  idle is a little lumpy but not to bad?
also when I was reving it hard to clear the ecu the oil light started flashing but the pressure on my seperate gauge was reading 3.5 bar?
 any ideas?

If you put this question in the right section, you might get an answer!

[heinz]

It is in the right secton as a 2E is a mk3 engine 

[raylee25]

Correct if I'm right.

Hmmm. I wonder want Mk2 means?

anyone else have an idea why my mk3 2E engine using the mk3 engine loom fuse box and dash clocks fitted to a mk2 idles at 1200rpm

Could be a faulty isv (idle stabilisation valve)mate, its in front of the throttle body moounted horizontally, or the throttle isnt closing fully. The black plastic bit of the throttle where the cable hooks on should come to rest against the alloy stop at the top when shut.

The throttle is touching the stop, will have a look at the isv in the morning
thanks

 Cleaned the ISV it was minging idle is now at 1000rpm
any ideas on the flashing oil light?

I think you need to clear the ecu dtc's and start again as it will record an error from when the idle was wrong and this triggers the oil light to flash. Mine did it because of the timing being out slightly. Heres a dtc scan from last night:

I cleared the dtc memory because the faults have been fixed now and no more flashing oil light. You can clear it by the following if you dont have VAGCom:

Disconnect the neg terminal of the battery for 15 minutes. When its reattached, turn on the ignition for 10 secs minimum (immob off remember)  so all the dash lights come on, after 10 - 15 secs switch off again and remove the key. This will clear the short term DTC memory and put the ECU in basic adjustment mode, where it re-learns the engine settings to factory standard. If you still have a fault even an intermittent one, it will record it again if it happens.

TPS (throttle position sensors) throw a fault when the idle is high too so that could be all it was and clearing the DTC codes would sort it
