was driving along & everyhing was running fine but then it started to pop & bang & hasnt ran rite since..can anyone shed any light plz

 

check leads ect and all connectors. starting will hall sensor on dizzy. i had the same problem and it turned out be si;icon spray, i had sprayed had gone thin in the heat and made it onto the contacts/terminals. give it a wipe/spray with contact cleaner and then id be looking at a new dizzy. hall sensor is integral with the dizzy unfortunatly. you may be lucky though.is the tps working ok?

 

btw what boost are you running and when were your plugs changed last? plugs dont last long with higher boost levels.

 

im not to sure of what boost im running but the plugs are new,new coil & leads & dizzy cap..

 

Check for a boost hose off, I imagine you have but just make sure! That's what happened when I popped a hose off.

It will most likely be something stupid!

 

Sounds like the distributor 2 me. Same symptoms as when mines packed in.
