Really rough idle to the point of dying. Then it may start up and run great for a while. It's been doing it for a while but now it has left me stranded too many times. The scanner says it has a throttle position sensor issue? What would be the recommended attack of this issue, what should I start on first? I do have a can of Seafoam in the gas tank as we speak.

 

Any ideas?

 

Nothing?

 

I can tell you that I had a rough ideling problem and so did my co-worker at the time I owned a 97 960 wagon and he owns a 99 c70.....one of my coil packs went bad and I had told him that I thought that this was his problem...well he spent several hundreds of dollars and still did not get this issue corrected, I recommend he take it to the local mineke shop where they will diagnose for free, he did take it to them and come to find out he had 3 coil packs that had gone bad and I recommend he replace them all so that the other 2 would not be an issue down the road....take a look at your coil packs this COULD be your problem...hope this helps, good luck!

Seafoam will not fix ur prob. If code reader says it's the TPS, then replace it w/ a new one. Go to IPD to check if they caryy it then compare the price w/ ur local
d(st)ealer. Be sure to buy d OEM
