mcvader Posted December 27, 2008 Share Posted December 27, 2008 So after all of the madness with blow by, getting parts, getting them installed and cleaning all the rocker arms for good measure I've finally got the jeep on the road. It's been a week and no major problems, although I'm kind of scared as to when it's going to die. Mostly because of this: when the Jeep has been sitting for a few hours, not being driven something occurs to where when I start it up, and get to driving around it almost doesn't accelerate at all from an idle position. It even sounds like it's going to just shut off (which it has done three times in the last week). Other times, it just takes it a few feet of motion then shoots off like a rocket after sitting at long stop lights. I've also got a breaking issue, same thing if it's been turned off for a few hours, I'll be driving about and when I apply the breaks it'll slow down then make a very loud oomf, or soft knock sound and jerk into a sudden stop. I'm pretty sure I just need new breaks for this problem so it's not as pressing. Any help would be appreciated Link to comment Share on other sites More sharing options...
Randy in Maine Posted December 27, 2008 Share Posted December 27, 2008 Would it be possible that the brake booser unit is leaking vacuum? You might be able to seal off the vacuum line that gives it the vacuum supply and see if it runs better. Link to comment Share on other sites More sharing options...
Pete M Posted December 27, 2008 Share Posted December 27, 2008 I'm guessing a faulty TPS. :hmm: Link to comment Share on other sites More sharing options...
mcvader Posted February 10, 2009 Author Share Posted February 10, 2009 Hey guys, I hate to bring up a dead thread but it's happening again,I got the breaking problem fixed (the shoes were cracked). The problem virtually went away, but I'm noticing a peculiar pattern thanks to the inherent nature of ridiculous south carolina weather. When it's cold outside, the problem where the Jeep barely moves when pressing the gas, then suddenly speeds forward is almost non-existent. But when it's warm outside (like today, when I went to work), the problem returns almost every time. At night, when it's cool and I go to the store or to a bar, it drives absolutely fine.

tmmoll Posted February 10, 2009 Share Posted February 10, 2009 I have the same problem, until the manche warm up you can floor the gas and not go anywere. I'm thinking it might have to do with a bad fuel pump, or gunk in the lines. Link to comment Share on other sites More sharing options...
Giffer Posted February 11, 2009 Share Posted February 11, 2009 sounds like a fuel to air problem to me, or just crappy gas. most other things i can think of would make it more consistent or at certain rpm's. but ive been known to be wrong once or twice.
