87 Runs like a dog.
Vettech:
Ok - thanks 77CVT for your reply.
I'm at work and set up to read the codes and got 33, 34, 36 aaand a 42222 what the - I expect a 43 not a 42, 43 is the EST - ie the module in the Dissy that changes the Pick Up (points) signal to drive the Primary Coil winding of the EHT Coil. Reading Manual. Ah haaa! the last time I did the Timing Light I disc the bypass or "Set Timing Connector", I must have left it open cct. No it was OK, but still had the codes - penny drops - disc battery - reconnect start codes again and sure enough all codes now reset. Start car - you can still here it running like a dog. Drive up street and give it some boot - still no codes but it is still missing and occasional backfire.
Now - 77CVT - thank you I have checked those items - the book also says check them as they are the most likely to cause issues. On ECM - yes it has a whole lot of stuff "HARD' programmed into it and you can change the chip to give other specs. But the ECM is only a Computer and can only give "X" if inputs "A ~ Y" have certain values. So a section of the memory is called "Block Learn" and as I said it sees what you are doing and sets the parameters for max power or efficiency or what ever you require - ie Dragging. BUT - this is volatile memory and if battery is disconnected the memory is wiped.

Don't shoot me for asking :bolt: However Fuel is o.k ? :leaving:
Vettech:
Ummmm! - Fuel - well there is only a range of 41Kms - so it is nearly out - this has been running like this for some time - and I'm sure it was filled at Blackheath on the return from some Bathurst Pub run, El President I think also filled up - Caltex. It drove home fine and back to the warehouse OK - and a few short runs into CBTN, then started playing up.
ONE Thing I have not done is remove the PLUGS. I replaced all leads. Took out #8, was OK - like brand new. But it was a PITA getting back in - I had the horrible feeling I was cross threading it ERRR. So I have not removed any of the others.
The fact it has still ample power and backfires when pushed could indicate one or two not firing and when the fuel gets into the exhaust it ignites - backfires.
Vettech:
NO NO - I'm talking rubbish - it was refilled for the Dam Xmas run - where !?!?. But ran OK - was only back in the w'house going for a short run or a test that it started this problem prior to Xmas.
But it could be fuel - I might shout it a new fuel filter.
