hi all just got my 90 240 not to long ago bought with a knocking motor (75 bucks can't go wrong) but im try to figure out what may be cause it ...oh and it also losses power at about 4grand i was thinking maybe the timing chain skipped a tooth on the sproket ......any ideas

 

Check your cars ignition timing ,btw are using 91+octane gas on your car ,put some 91+ (93 would be better) octane gas with octane booster on your car and see if it still keep knocking,after that let us know if it keep doing it.

 

ok cool i'll ck the timing and put some high test in there...what about octaine boost

 

Get NOS octane booster,get either the Racing or Off Road formula ,,they do help!

 

^^ i'll try that to

 

all righty keep us inform then

 

I think it's your ignition. check spark plug, wire, distributer... ext

 

ya know what on of the spark plug wires that from the distributer to the coil does look broken but the car starts and runs at a decent idle

 

Ignition coil can be to blame too! (I'd replaced everything & still had it- one $40 part later & my E was purrin' )
