you do that then, but you can read several testimonials on this site that complains about them. i put a set of bosch plats into my 95' chrysler cirrus, cylinders 2 and 5 fouled the plugs up immediately. i made sure i got my money back, cause anyone who has experience with that car would know what a PITA it is to get to the right cylinder bank. intake plenum had to come off, but of course there were 2 mounting bolts that sat behind the engine, and it was transverse set up, and i dont have 2 inch diameter arms either... the difference between copper core plugs and those useless platinum plugs is longevity of service, platinum lasts a lot longer apparently. however i don't mind replacing my copper cores every 10,000 miles. this way i know i'll still be getting the best performance out of my engine, and on the bright side of this, each spark plug tells the condition of how each cylinder is running based on it's color and physical condition. IMO, copper cores pay off.

 

ok well ill run these till she gets running ok then anyway i got the code so if you guys could tell me what to do it would be great the code is p0121 and it says the c,o,oh are blinking

 

P0121 (M) TPS Voltage Does Not Agree With MAP TPS signal does not correlate to MAP sensor signal.

TPS signal does not correlate to MAP sensor signal.

sounds like the throttle position sensor is shot

get a chilton manual, it will tell you how to test it without the DRB scan tool

 

check the voltage on the sensor thats all you need to do 0.70 is about right I think. Check the tips and tricks it's sticked to top the somewhere...

 

so if i replace the tps and possibly the map sensor do you think it will solve the prob ?? i dont want to do a fix thats gunna last for 5 min i want it done and done right along with the engine running properly if i have to spend 150 for them both new then so be it

 

Do this first. As previously stated the ideal is around .70. If it fails this test then start by replacing this sensor, then go from there.


The TPS can be tested with a digital voltmeter. The center electrical terminal of the TPS is the output terminal.

With the ignition key in the ON position, check the TPS output voltage at the center terminal wire of the connector. Check this at idle (throttle plate closed) and at wide open throttle (WOT). At idle, TPS output voltage should be greater than 0.26 volts but less than 0.95 volts . At wide open throttle, TPS output voltage must be less than 4.49 volts . The output voltage should increase gradually as the throttle plate is slowly opened from idle to WOT.

 

alright ill check it and see so the middel is positive then what just ground the other ?

 

the middle is signal, not positive, connect the positive lead of the digital multimeter to the middle terminal and find a good ground to put the negative lead to, a good ground will be anything metal, just use the tip of the probe to etch into your ground to have a good connection

 

tps wire reads 4.68 at idle or wot ??? so now what do i do

 

idle = .26 - .95 volts

WOT = less than but up to 4.49 volts
