How would you go about diagnosing this problem...

[quote=“somedude,post:14,topic:29575"”]

that car was a piece of work that is for sure. i yould like to lend a hand if possible. i can grab devins timing light and we can figure out weither it is a injector or spark problem. I would almost lean twords a injector at this point. i get out of work at 5:30pm give me a call.

i think the only cure for that curse is boost.

Timing has been checked a few times…fuel injectors have been tested both in the car and on a bench. They passed. Thanks for the offer, tonight won’t work for me but perhaps later on I’ll let you be the next contestant in this game of “fix the SHO”!!!

Whatever is happening isn’t a constant…i.e. fouled plug, dead injector, etc. I can clearly see the fuel spray into the cylinder head, plugs are all okay, plug wires all tested good outside of the car.

Next step is a leak down test…
