EFI computer codes V8

[RhinoW]

hi, when i bridge the ALDL connector terminals the engine light flashes fast 4 times and then pauses then 3 times, just wondering if anyone knows what that code error means? When the engine is just at idle it seems to have a vac leak because it starts to stall and then it correts it self. Would like some help please. rhino:banghead:

if anybody needs to know error 43 is the knock senser, thats what my problem is.

it depends on how you read it, it could be 34-MAP sensor voltage to high, or 43-Knock sensor open or short circuit.

make sure you read it properly or you will be chasing your tail.

fault codes will start of flashing, then slight pause then flash again, then long break and then start code again.
