#1662 of 2544 CEL & surging mazda 626 2 lt 1994 atx by mazda626atx

Apr 16, 2005 (5:15 pm)

When running car (parked) to warm it up pre testing, it is almost impossible to maintain 2000 rpm . Get near 2000 then surges to 2500 and then when I try to back off it drops back to 1500. I know people have mentioned surging here but only happens when not under load. Also CEL used to come on only under load (uphill accelerating etc) but since I have installed xternal trans cooler, now it comes on at lower speeds, stays on longer and occasionally stays on till I come to a full stop at a light. Any ideas ?

Some kind of fuel delivery issue...sounds like its running rich. Do you have somewhat disappointing fuel mileage on this car?

Thx Mr Shiftright. I am in NYC at the moment . I am going to have wife do a mileage check before I get back . This way if I need parts I will bring them with me when I go. I sense the mileage was dissapointing but I thought that was more due to my aggressive driving style. Plus I never really checked because gas is sold in liters there so I will have to pay attention and convert to gallons.What type of highway mileage should I expect . Also mixed city freeway driving. If its running rich what might it be ?
Thx PGP

well it'll have to be diagnosed more carefully. There are no error codes from a Check Engine Light? Usually some sensor or valve gone awry and messing up the fuel mixture.

I get a 159 MAF and a 181 (lean condition) or 118 (ECT). I was rushed when I got these codes and it was my first time. I will have to read them again when I get back to Greece and I hope to get better at recognizing them. I was curious if the surging to 2500 then dropping to 1500 might confirm something, because I am considering buying parts here before I go back and have an opportunity to retest. I cleaned the MAf and checked all the wiring and will either buy a new one or wait till I get there and have a shop check it out with the info I now have.
   Also I was wondering what sensor would become more sensitive by adding external tranny cooler as I mentioned in post #1642. ( The whole scoop on the car is in this post ) Its sorta tough cause I dont have a parts store there , so I have to sort of guess what I will buy here and take with me.
Thx again PGP

If we're going to get into codes, you should prepare your question exactly and then post it here,where it is more likely one of our visiting techs would see it.:

Hi there, do you have solution for code # 113 ?
There might be a few causes: I drove a couple of miles (about 20) with gas light on (according to the spec) and I changed air filter at the same day.
Please, help:)
Thank you in advance!
 
P.S.

What was the check engine code? It could be a sensor in the transmission- 626s are notorious for tranny problems if it's an automatic. Did you check the fuel filter?
 Also try cleaning the MAF sensor. Mike
