Sputtering and misfire all of a sudden

So I let the car warm up for 20 mintues, drove it down the street 3 miles or so. Parked and let it run for 5 mins. Then got back in to drive back home and next thing I know getting into boost its starts to backfire and sputtering.

 

I'm gonna run a check on the error codes when I get home today. Could the culprits be the Secondary injector, or FPR?

Yes the secondary injector could cause problems like that. It's most likely the wiring to it, if it was fine before you did the seals. Make sure you didn't accidently mix up the connectors.

 

make sure you didn't put the wrong connector on the wrong injector and make sure the injectors are in the right slots. my primary is bad and its doing exactly what you are describing. I would ook at the injectors and check yer FPR witha might vac to see if its holding vacuum. If it is and you don't get a bunch of fuel coming out of the vac line on the bottom of it it should be good.

you can use this topic to clean and test flow your current injectors. and it also gives you a great source for new ones if you dont want to rely on 20yr old ones.

one thing you dont want to do is let a turbo motor run lean, thats a big no no. checking and double checking your fuel system is a must! a fuel pressure gauge is a good idea also.
