This car is beautiful, but has problems sensors.I would step on the gas and it would not acclerate..or the car would start backfiring and sometimes turn off..and i had to let it cool down then it work perfectly again...weird?I even bought a new fuel pump thinking it was that but no..it kept happening so I've changed (paid) for the coolant sensor, camshaft sensor, new engine speed sensor, thermostat assembly..and car is running perfectly now but still has the check engine light on.I bought the solinod sensor cuz i read somewhere that that part causes the car to backfire so i bought it, but have not installed it yet. When i take it to check what it is..they give me multiple diagnoses..engine misfire, coolant sensor, oxygen sensor, thermostat...they ask me if it overheats..but it doesn't so they say start with the cheapest part to find the problem...Luckely my dad is a mechanic so he puts the parts on it, so i don't pay for labor =) but still my dad is there for hours trying to figure out where they are and if that's gonna solve the problem.

does anyone else have this problem?...I took it to San Antonio and to Corpus and use it everyday and it works perfect now...but i just hope this doesn't start again...My car has 116,196 miles and i provide excellent maintence to it, regular filters changed, oil, tire rotation/alighnment, wipers, new tires, battery,new spark plugs, tie rods,banda..it's in excellent shape it's just the sensors =0

The third out of 4 Oxygen sensors to be replaced. When one of the Oxygen sensors goes out, the car becomes almost un-driveable.
