#1882 of 2476 Re: erratic idling and engine check light on [rohangrover] by alibub Sep 29, 2005 (12:14 pm)
Replying to: rohangrover (Aug 19, 2005 4:30 pm) I have a 1995 Mazda 626 with close to the same problems you are having. Mine use to surge for no reason on the highways and a few times in town for no apparent reason. I had it checked four times by Mazda under warranty back in 1996. They could find no problem, they must have thought i was crazy. It happened again and for the fifth time i brought it back to Mazda, i told them to have a mehanic take it for a long ride on the highway and after 45 minutes the same thing happended to him. He stated it was a problem with the inhibiter, no idea what that is. They ordered the part, put it in two days later and i have never had the problem again.

Replying to: alibub (Sep 29, 2005 12:14 pm) Could you search your records and maybe find out the part number. Or call the dealership and find out part name or number. It would be helpfull to me and many others in this forum.   I keep all my auto records, hopefully you do too.  Thanks In Advance PGP Replies to this message: junky626 (Oct 25, 2005 9:41 am)

#1885 of 2476 MX6 1990 Stalls by talkcars Oct 10, 2005 (3:41 pm)
1990 MX6/automatic trans/75k miles. Car stalls in drive when slowing to stop. No codes detected when connected to computer. A mechanic suggested checking/replacing the idler or something like that. Any suggestions on the name of this part. Thanks.
#1886 of 2476 626 4-cyl 1999 Cyl one misfire by chrb Oct 12, 2005 (8:33 pm)
Hello everyone,   I've been following advice posted by others on this board and I'm running out of options. My '99 626 started to misfire a few days ago. It's done this in the past, but replacing the plugs solved it then. The latest set has been in for about 2 months and was replaced at the same time as the fuel filter. The problem only happens when accelerating. The code reads Cyl 1 misfire, but it feels more like all cylinders misfire at the same time when this happens. I cleaned the MAF earlier tonight. It was pretty clean and did not solve the problem. I'll replace the year old plug wires tomorrow but doubt if that will fix it. Any other suggestions for what seems to be a common problem. Kind thanks Chr B. Replies to this message: chrb (Oct 13, 2005 7:17 pm)

Replying to: chrb (Oct 12, 2005 8:33 pm) I replaced those spark plug wires today, and that fixed the problem. Unbelievable! I never thought that wires could deteriorate to such an extend in a year or two and that it could have such an impact on the engine. Well, hopefully this may help someone else... Regards Chr B.
#1888 of 2476 92 Mazda 626 High and low compression by dougsbart Oct 17, 2005 (9:11 am)
I recently aquired the 92 626. #1 Plug was blown apart, compression test showed about 150 PSI in #1. #2 had 0 PSI. So i figured it was a head problem. Took off and re-worked head, replaced and still had about 150 PSI on #1 and only about 60 PSI on #2. My son has been driving the car for a little while, just a back and forth to school car. Last night "boom" blew #1 plug apart again and no compreesion on #2. I am trying to figure are these problems related, or are the rings bad in #2 and no relation to the unusually high compression in #1? Is the head bad, maybe cracked somewhere that I missed? Incidentally #3 and 4 are what I would consider normal at about 100PSI. I have never seen a plug blow out like this before.   Pls advise, Thanks, Doug
#1889 of 2476 Transmission not engaging. by bohook Oct 19, 2005 (8:34 am)
I have a 1999 Mazda 626lx with automatic trans. Upon returning to my car I started the engine and put the car in reverse but the engine just revs. I can select drive, and reverse but I can't feel the trans engaging. The shift selecter seemed a bit loose so I checked the linkage cable in the interior and it moves with the selecter . I'm unsure how to identify the same cable under the hood. Am I on the right track? Any suggestions? Replies to this message: mposeyms (May 12, 2006 10:36 am)
#1890 of 2476 Re: 91 626 [cheese_dip] by 626er Oct 21, 2005 (6:06 am)
Replying to: cheese_dip (Oct 05, 2005 6:41 pm) Good bet that the MAF is bad if you are having to prop it open and allowing a very rich mixture. Also, be sure to check the throttle body hose for cracks. My 90 626 ran lousy. Never could find the problem. Replaced the MAF with one from salvage yard (recommend go to reputable yard) but still ran rough. Finally pulled the hose and discovered large crack in bottom of hose. Couldn't see or detect it until I took it completely off. Replaced hose (again from salvage yard) and engine perked right up. Be sure to disconnect the batttery before you remove the MAF and take care to remove the MAF connector clip carefully. Total cost: MAF $55, hose $10, running smoothly - priceless!
#1891 of 2476 90 626 tranny woes by underdhood Oct 22, 2005 (12:17 pm)
Proud owner of 1990 626 LX. V-6 w/175,000 miles. A/T with the economy/power mode select. Have had a problem which has gradually gotten worse. From a stop, with light to standard acceleration, the 1 to 2 shift is accompanied by a huge BANG. It is like a SAM missile hits the left front of the car. Any possible "Hail Mary" fixes i.e.; band adjustment, governor replacement, sensor failure? Or is this the sign the Old Faithful is now swirling around the drain? Am from old school, where you don't change fluid after 100,000 miles. So I'm a little learry of pulling the pan unless it gives up completely. The Dr's oath, first do no harm. Thanks! ps: does this have a lock-up tourque converter? If so, does it have it's own wiring harness?
