well said rainman. The entire idea of forums like these is to share ideas/educate and solve shooting problems of one's car. So fellow tuners won't get run around and spend big $$$ on what could of been easily diagnosed by a solved issue.

hear wat eh fellas,i had that dead car syndrome problem no one here seemed to know what wrong, did some reading on the net it seems that these bj, zl or zm after awhile starts losing power, one solution is to manipulate the ecu to give more air and gas i did it and i flying, 50% increase in hp,no kiddin, so when u all see a green hatchback pbh doing it on the CRhighway is me, u all have to mod to get that car to run otherwise is problems.

and how exactly you modded the ECU?

Rainman · Postby **Rainman** » February 2nd, 2010, 8:09 am

He stuck a mazdaspeed decal on it, 15+ HP YO!!. If a car is not operating in its normal manner it means that something is wrong, "modding" or making changes to the vehicle that were not part of it's original design will not fix it, it may actually make it worse. Fix the problem, don't add to it.

Check yuh knock sensor. Don't know if the ZL has one but i had a similar problem on a ZM and it turned out to be a faulty knock sensor. If it has one check to see if the insulation is melted, if so you should change for the upgraded sensor with the black wire...my two cents.

or just unplug it for the while and see how it runs...

i seein a slight oil drip from my knock sensor, anybody know wat could be causing this?

Groovemaster · Postby **Groovemaster** » March 30th, 2010, 12:51 am

^^^IT GOING THROUGH!!! That's how my lost in power started...with a molten, 'leaking' knock sensor. I had problems getting up hills & to overtake...not getting 'kick down'. Changed knock sensor & prob solved!
I'm doing 67k & had a bad knock sensor, somehow I feel mazda just change the colour of the wire & send it out as 'revised'.

(Thanks 2 Villain for pointing me in the direction of the knock sensor)

thanks Groovemaster for the clarification, i really find the kickdown was sometimesish

Don't study it man we all in this together. Just do my routine PM on my car and it seems 2 engine mounts and my bushings gone. Have to change timing belt and tensioner and idler as they are suspect to me and tapping head seal seems leaky. All I can say for this list is and going......I think is time for the poly bushings. :twisted:

If he has manual & unplug it that's ok but if auto the ecu would leave you climbing hills in 3rd gear!!!

you mean to tell me that you have had this problem for five months and you haven't done anything because no one here can figure it out for you?

START BY SCANNING THE FACKING CAR!!!
