I had a leaking injector but decided to buy 8 flowmatched from bosch via ebay instead. The original part nr is 5235301 and the new ones from bosch has part nr 0280150943. Both 19lb injectors

But now after the swap the engine starts, revs up, then immediatly dies. If I give it a good deal of throttle I can keep it alive but only at very high rpms.

Any ideas? Is it typical for a vacuum leak? I wouldnīt be surprised if something is not assembled correctly...

Wrong injector type?

Please point me in the right direction.

Itīs a 305 tpi by the way.

 

Checking for damaged or worn plenum gaskets would be a good start.

 

Ok, I will do that. Sounds like vacuum leak is a likely cause of this.

 

Problem solved! Cold start injector was not seated correctly. Now itīs running like a charm.
