Psych0matt Posted June 13, 2006 Report Posted June 13, 2006 So, if my egr tube was messed up (ie, not sealed) would/could it make the car lack power and run kinda crappy? Quote
slick Posted June 13, 2006 Report Posted June 13, 2006 It could. A truely faulty EGR valve will cause bad gas mileage and a rough run. But, in most people's cases, they just need to clean out the carbon that go's from the intake to the EGR valve itself. Quote
Psych0matt Posted June 13, 2006 Author Report Posted June 13, 2006 well, I had to make an adaptor for mine (new block, old intake) and I think it got hot and isn't sealed anymore Quote
slick Posted June 13, 2006 Report Posted June 13, 2006 I would just talk to Ben about making you a chip so you can completely forget about the EGR. Unless you need it. What got too hot and isn't sealing anymore? Quote
Psych0matt Posted June 13, 2006 Author Report Posted June 13, 2006 i had to use jb weld when i put the two halves together because I was running out of time. i don't think i got it good enough Quote
Dirty Rockstar Posted June 14, 2006 Report Posted June 14, 2006 On the EGR front: My experience in recent months has been lower gas mileage, even with AC off in the warmer months.. Also, a slight smell of gas, like the thing is runnin rich.. And a slight lack of power.. I can hear a slight exhaust leak coming from up near the front I need to look at.. But the biggest flag is the car will throw an SES light at me, for no more than 15 mins.. Then it goes out.. I had a friend hook up a scanner to my port and oit was found to simply be a faulty EGR Soelnoid.. Cleared the code(s) and the SES is gone, but the rich smell is still there.. Matt, do you get an SES light? Quote
Brian P Posted June 14, 2006 Report Posted June 14, 2006 I've been running with the EGR out for about 2 weeks now (awaiting a changeover) for the record, my fuel economy hasn't changed. If anything it might have gone up a slight bit. Quote

Brian P Posted June 15, 2006 Report Posted June 15, 2006 the slight increase is probably a coincidence. But by no means have I seen a decrease. Quote
Psych0matt Posted June 15, 2006 Author Report Posted June 15, 2006 about the ses light, I really don't know. I think either my bulb is burnt out or i missed a wire when putting in the UB3. I just realized that a week or so ago, it doesnt light up with the start up sequence. and of course, autozone cant scan a 94 (i even double checked while i was there today) Quote
skiiirt Posted June 15, 2006 Report Posted June 15, 2006 When my speed exceeds 50mph and then drops below 50mph my SES light will be thrown. Its is a 32 Every time. If I am driving 50+ and stay above 50, no SES. I know exactly when the SES light will come on. When the light is on my car is running 60% and will not run normally untill the car is shut off for 2 minutes or more (unless the engine is really warm). Because of this I stay away from freeways and only use highways when necessary. I can burn a 1/4 tank of gas driving 20 miles if the SES light is on. Quote
Psych0matt Posted June 15, 2006 Author Report Posted June 15, 2006 My egr tube was definitely in two pieces. I had to make one myself (new block, old intake) and i jb welded it, and it shoulda held up fine, but it looks like the guy that dropped the engine in for some reason took it apart, put a piece of pipe around it, and then siliconed it. I put some silicone adheisive junk on it for now, since that's all i have, and if i warm up the engine to drive to the store it will defeat the purpose Quote
