Acceleration Issue

[ralphsdiorama]

Hey guys, well recently I have had acceleration issues with my car. A few months back I blew a fuel injector and ordered a stock 370cc replacement. I replaced the dead fuel injector and the car now idles normal again but under acceleration the car has what I call a "twitch." When under full throttle the car will start boosting but then it kind of bogs for a second, backfires a couple times, and then continues to boost to normal levels. Please nico doctors help me diagnose my baby!

Have you checked for boost leaks, or vacuum leaks?

I have looked but found nothing so far. Could it have anything to do with the new fuel injector I installed or do you think it is most likely a vac leak?

Run a boost leak tester. Also, soap and water on the vacuum lines. Have you also checked to see if you're leaking from an injector?

Found boost leak and fixed it. Everything runs fine now! Thanks duffman!
