| For all of you 1994 chevrolet astro owners and any others that have the older 4.3l vortec engine. i have the solution to your legr valve carbon cloging problem. my 1994 ext van has 150,000 miles and i had been getting the rough idle and stalling when at a stop light problem. it has done this before to me every 6months or so and i just pulled off my egr valve, knock out the carbon chunk that is stuck in it and 20 min later im on my way. well it has come back bad and it is cloging every 20 miles with lots of carbon chunks. chevy tells me that the lower intake needs to be emoved and bead blasted to remove the carbon build up. i did some research and there was a egr recall that they were supposed to take care of this cleaning if it happened the 1st 7 years or 75,000 miles of the van. well they wont do it for me and the dealer wants $500-$1000 to do this. i fanaly found the solution to this problem that every chevy owner that has the 4.3l vortec eninge. this is called the klean screen. it is a replacement egr gasket that has a high temp screen at the egr input opening that will stop large chunks of carbon from entering the egr valve and when it gets warmed up the screen will break the chunks up into small peices that will pass the egr poppet. they cost about 13.50 each at auto zone and the company is named tomco inc. www.tomco-inc.com. it has been 1 week since i have installed the gasket on the original egr valve that came with the van new 150,000 miles ago and it runs great so far. th gm part number for this gasket is 2-1357. i bought mine at the local autozone by my house in virginia. you can also buy right from the company at 10.50 each with a 5 order min. good luck everyone wayne jordan. *ak | |||

| On feb.1997 i received in the mail a letter from chevrolte stating that they werer having trouble with the linear exhaust gas recirculation (legr). if my vehicle was having trouble with that to please bring it into a chevrolet dealer and they will fix it , no charge. they provided me witha special warranty coverage which stated:seven years or 75,000 miles whichever comes first, the condtion will be repaired for me at no charge. i had no problem with that ath that time but since then i have, in total, to this date (11/15/00)have had three(3) different legr valves replaced in my van. the first on, sept. 12, 1997, the second one, jan.26, 1999 and the third one, nov.15, 2000.every 2 years theis legr valve needs to be replaced. my van as of today has 70,000 miles on it and is 6 years old. in another 2 years if my van needs a legr valve, i will have to pay out of my poclet to have it fixed. i don't feel that chevrolet has fixed the problem once and for all and i want to know if there is any recourse if this problem happens again. i feel that if chevrolte has had 3 times to fix this problem, and if it happens again, i feel that i should not have to pay to fix this problem out of my pocket because chevrolet has not fultilled their obbligation to tix this problem. could you tell me or give me guidance as to what cand be done about this? thank you. *ak | |||
