Had a hose burst on the CS which sprayed antifreeze all over the front offside engine compartment!
It was the 3" long 3/4" diam water by-pass hose to turbo. (under the turbo to IC pipe) What a boogar to get a 3" long pipe into the 1" gap between pipes!!! :?
Never mind, sorted now :)
I managed to wedge the IC far enough back to access the hose and do not believe I did any damage to other pipes or dizzy/leads.
However!!!... now she starts fine when cold (or hot) and revs to circa 1200 but on reaching normal operating temperature the revs drop to 3-400 (used to be 7-800) and she stutters. She will not pick up on throttle without a struggle, popping and banging as well. If I hold her above 1000+ there no problems at all???
Heel and toeing is a misery!
I was wondering if the electrics around the alternator or the O2 (4 wire) sensor connection (which got soaked in sticky yucky wet stuff) might shorting and miss-informing the ECU?
Should I wash these with clean water and dry off? OR... could I have nipped/split/knocked something else behind the IC when I pushed it back?
What you reckon guys?
Thanks in advance for any theories :lol:

If it runs fine at higher throttles then I'd suspect an air leak, maybe a split intercooler pipe or a small pipe pulled off somewhere. Maybe even the old favorite turbo to AFM pipe if you disturbed it moving the intercooler.

The only electrics in the area that could cause this would be O2 sensor. The connections are meant to be sealed in the plug & socket but seals or latches may have degraded. Wash with clean water & fully dry (with warm air) before any re-assembly.

Cheers boys :) I'll double check for air leaks and 'wash and dry' the o2 connector as it did get soaked!
That sign looks familiar???? Normally hung around wor lasses neck :(
