check IAC, TPS, CPS and CSPS

Thank you I have recently (2 weeks ago) changed my Crank Position Sensor. any easy way to check the TPS or IAC

You need to have the codes read stop by a Auto Zone or advanced Auto parts and have them read for free and post here for help....

will do Thanks everyone :)

Hello What is a CSPS?

I thought that CPS was the crank position sensor...if CSPS is the sensor then what is CPS? Thank you

My apologies...so they are both different?i thought they were the same. i did change the cps where is the CSPS located? Thanks again

Hi everyone I ran a scan and it reads no codes But what it did display on my below my speedometer was start error I turn it over and it runs for a sec then stalls Going crazy R

When it first started having problems it drove great then a couple times chugged like the choke was on.Then it drive ok and finally stalled. It would start idles slow then high then stall. M Now it starts then dies

My battery is dead and I am using a boost...would that make a difference in the reading I unplugged the maf to see if there was a difference..not

I did notice a few weeks back it would idle slow at lights where I thought it may stall but it never did.
