weird shudder

[blackeclipse]

I got the boost leak in my car fixed and now when i floor it in 2nd 3rd or 4th everything goes fine until 3k rpms then it will shudder a sec and go back to normal. Sometimes it shudders a couple times but acceleration is fine all the time unless it's in the middle of shuddering so what's going on?

I just recently had a similar problem with my car. Everything would be cool until I hit boost, then it would shudder like mad crazy. Almost like it was missing, but no backfire. I fixed my problem when I changed my fuel filter. Try changing the filter, and if that dosn't help it, look somewhere else in the fuel system for your problem.

how difficult and how much time to replace?

PITA. Leave it on the firewall when you break the nuts on top/bottom loose. It helps a lot. I didn't, and i ended up re-fabricating fuel lines

it's under the battery to the driver side

so go from under the battery and over?

Have you ever opened your hood?? ......yeah, remove the battery, and its right there!! Its about 4 inches long, BLACK, and has 2 fuel lines attached to it. Anyway....I am having the same problem, and I changed my fuel filter and that did not work. But it defenitely feels like a fuel problem. Only does it under load. Good luck with yours.
