Here's the story....
We have an '88 Tarago GLS :-
Left Bendigo on Thursday went via Seymour and had cruise control on and running a 105 kmh up the Hume to Albury - filled up at albury and as soon as we got back on the Hume the "Check Engine" light started coming on intermittently - it would flash on briefly then stay off for 50 - 60 kms then flash again.
Spent the night at Yass and filled up again - got to just north of Goulburn and switched on cruise control again and first kickback on a hill had the dreaded check engine light flash again - switched off cruise and only had it flash twice up till Sydney.
Filled up again in Sydney - didn't use cruise control but had the light flash once between Sydney and Port Macquarie - this was when overtaking a truck up hill on the Pacific Hwy before Newcastle.
Anyone have any ideas what may be happening ?- our thoughts were fuel - maybe Ethanol in the unleaded ? - but to be honest, we really don't have a clue - if it stayed on we would probably have a better idea, but the intermittent coming on has us stumped....
Any speculations welcome!
