ok now i got another issue with my 7. just got me rear end fix a couple days ago now another demon decided to show its ugly head. when im on the road my car tends to "PAUSE" basically when im driving the car loses fuel then 2 sec later it turns on again. and everytime this happens my car jolts violently then when i turns on again i get a loud backfire from the exhaust. i dont know if its the fuel pump or the ecu. wiring... just dont know.

 

Sounds like electrical. The backfire is the raw fuel igniting in the exhaust sytem. If it were a fuel delivery problem, there would be no fuel to ignite.

 

Sounds like a bad or untuned TPS. Does your dash panel idiot lights come on? If not more likely TPS

 

sounds like bad battery connections and maybe the alternator charging wire. if the voltage went below like 12 volts all the warning lights would come on. are the warning lights coming on?

 

Umm dood that is exsactly what I asked him.

If the ALT was bad it would be bad. If it is bad the car wont stay runing when batt dies and he will have to charge it to start car or go anywhere. If bad battory then it wont start b/c no power but will not efect warning lights as when runing ALT will controll them.

 

i had problems with my battery connections a little while ago. the car would start, but once you moved, it would cut off and then cut back on again while driving, jerking the car violently. turned out just to be a bad battery connection (positive). make sure you clean the terminals and posts, and then make sure the terminals are making a good connection.

 

i went to mazdatrix today and they told me it was the TPS so now i have to find a use one. anybody have have an idea how much they cost?

 

Around 50 I believe
