  1. @admins PLEASE DELETE THIS THREAD. New updated thread here...

  3. Loping idle. 2002 Mazda 626 V6 2.5L. Video below. Making a new thread because a lot of updates since last time. New fuel pressure regulator, new EGR valve, new MAF sensor, new throttle position sensor, new PCV valve? Still same problem. Video below. Any other ideas folks? Please advise. Should I junk it?
  4. 2002 Mazda 626 V6 2.5L Car ran great no issues. Parked it. Two days later went to drive it and car cranks but will not start. Fuel pump is running. Spark plugs have spark. Fuel pressure regulator brand new, Mass Air Flow sensor brand new, throttle position sensor new, EGR valve new. PCV valve new. What gives? Please assist? I'll post a video of me cranking it if it will help?
  5. What was the result JoMo? I'm having exact same problem. 2002 Mazda 626 2.5L V6 Ran great, then after letting it sit for a week, tried to start mine and now it cranks but wont start. Fuel pump relay is fine. Fuel pump is pumping fuel. Fuel pressure regulator is brand new. Spark plugs are firing off. What gives?
  6. Thanks for the suggestion... is this a hail mary .... or ?
  7. Not really trivial. Took it to a mechanic... $200 later they said it was EGR valve. I dropped another $200 and replaced the EGR valve. No fix. Several times during use, had to crank the car for 2 whole minutes to get it to start. Pretty pathetic. Went from 30 mpg to 19 mpg. And on top of that no one on this forum after 9 days seems to have any idea what the issue could possibly be. Yeah id say its junk worthy.
  8. 2002 Mazda 626 2.5L V6 Was throwing the P0400 CEL code (EGR code). Also had a lopping idle and ran rough and started rough. Replaced EGR valve with a brand new one. It fixed nothing. Exact same symptoms and issues. Any thoughts before junking this thing? @admins PLEASE DELETE THIS THREAD. New updated thread here...
  9. Thanks for reply. I'll replace it. If that doesnt fix anything and assuming the EGR is still good... what else do you think it could be? Also, by rough idle I mean a loping sound. It is a different sound then, say, if I remove the #2 spark plug wire while running. Then it is an additional clicking noise sound (of the cyclinder #2 not firing) while running. So I don't think it is missing at idle.
  10. 2002 Mazda 626 (2.5L) has rough idle and RPM dips up and down going down drive way in first gear. Also, sometimes takes A LOT of cranks to start. This issue has been degrading over time. First it was just rough loping idle. Now I have problems starting. I crank it for a while and then fires up and then dies. After a minute or so of cranking up and dying... it finally cranks up and I am able to hold at 2000 RPM until the idle is somewhat stable again. I have also noticed a lack of power recently. Plugs and wires are new. Check Engine light is on and has been for a while. the 4 Check Engine codes are P0400 - Exhaust Gas Recirculation Flow P0300 - Multiple Misfire Detected P0302 - Cylinder 2 Misfire P0305 - Misfire Detected I removed and tested the EGR valve (very difficult btw), and according to procedure in Chilton Shop Manual... the EGR valve is good. Any ideas?
  11. .... annnnnnnnddd .... nobody knows.
  12. Now my mazda is doing the same thing as what my dodge is doing.... pressure is going back and forth all over the place. I have both vehicles vacuumed and charged to the factory amount. I didnt loose any vacuum overnight so I assume there is no leak issues. I also tried adding an extra 100 grams later on and it still does the same thing. I charged it the same way this guy does it....
  13. OMG YOU ARE AWESOME!!!!!!! It worked!!! Unplugged it, blew in it, and plugged it back up and the code is gone. I'm already $61 in the hole for a code read and failed state inspection and I'm glad I don't have to waist anymore money on this thing.
  14. The aftermarket downpipe is straight. The factory downpipe has a large bend/hump in order to get by a cross-beam. Therefore the aftermarket downpipe must be bent quite a bit in order for it to even come close to working.
