hi all thanks for the reply so far

ive had another look at the van this weekend i put a slick50 (oil treatment )in which has stopped the engine from knocking ,ive also cleaning all the earth points and connections it now starts sometimes and doesnt stall as much.

the ecm in van is a sevice number 16144288 auln *86aulnkb21491841* 16151111 and ive also got a 1988 astro with 4.3 v6 tbi engine and the ecm is service number 16144288 aumh *86aumhk300890391* 16151241

can i swap them over to see if that is the problem ?

thanks damien
