I am looking for a new Mass Air Flow sensor , since mine is pretty much FUBARed. My car is a Kia Sephia 2000 LS (with 1.8L DOHC engine if I remember correctly). My car runs sluggish during idle but normal driving is unaffected (since I modified the hell out of the intake system just to cope with the sensor). Sometimes the car stalls or shuts off, and other times it bucks. I made sure the sensor is installed correctly and flowing the right way, I took off the negitive ground for 15 mins to reset the computer and to recalibrate the system. I also added a few home made ground wires. I know its the sensor since one of the chips inside the sensor that measures the air is chipped off. So its basically half a sensor.
here is what I did to it so far:
Mind you I got this car in shambles, I had to replace alot of the hoses since they were rotting, I also had to get rid of the stock battery cables since the termals that connect to the battery were crackinga bout about ready to break (they were rusted and I had to sand them, they look like they use some sort of brass and aluminum combo but I know its just aluminum). I replaced them with some heavier guage wiring, sanded both the contacts of the new cables and the battery terminals. I replaced the break air bleeder hose (the one that connects to the carb) since the lines kept getting too much air bled into the lines (helps with braking alot). I also installed a modified intake system, I also took out alot of weight (atleast 100+ pounds of extra crap.) Replaced the spark plug wires (gonna replace the coils and the wires with higher performance ones, or atleast the wires with 8/9MM or higher), Dropped in some Bosch Platinum 4+ spark plugs (what a difference! The ones that came with the car were stock NGK plugs that were worn and had high speed glazing on them). I also did soem hand detailing (engine compartment cleaning which made a difference when working inside the car, alot easier).
now mind you that the car was just all trashed up when I got it since it was originally driven by my sister who lived in the HOT climate of vegas and from what I heard, she drove the heck out of it. Now im stuck with replacing parts on the car, but none of the less I have a blast doing it. I really need that MAF replaced, its really making me not want to drive the car since the jerking is annoying and I don't want it to stall when I stop at an intersection or something.
The Kia place here in Southern California (located in Temecula) says that to buy a new sensor, its gonna cost approx $232.87 and they quoted a price of $90 for new coil packs, and thats if I install it myself, im sure they would gouge me if I were to let them install it (whats the point, I am mechanically inclined). I think those prices are more then bogus. Is there any place that I can get reasonably priced parts, stock or Aftermarket (aftermarket preferrably but stock will do)? I really don't want to have to fork out such a huge wad of dough, if none fo you knows of a place (online or retail, doesn't matter to me) then I guess ill roam the junk yards, and if that doesn't work, then I will just fork over the dough and suck it up.
Thanks for all of your help, its nice to have something different instead of seeing everyone drive around with Riced out Hondas (everyone has one). Atleast my car isn't as common as dirt and far cheaper. Also I figured that Modifying my Kia would give me the best challange (since its harder to modify it, it will force me to learn more about cars) and it also makes for a good, worthwile project, if anyone has any tips for modifying Kias besides KFPerformance or Kia-FX then let me know.
one last question, how easy is it to install a free flowing (Flowmaster) muffler, I know that the piping uses 2 1/4 Inch piping but do most mufflers work, and if not how would I go about modifying it to work if all everyone has are 2 1/2 Inch or 2 Inch muffler/piping?
