I have a 04 s60 2.5 t. With 190000 miles. It's started displaying reduce engine performance and going into limp mode intermittently but I was still able to drive on the freeway. I would just put it into neutral without pulling off the road and turning the car quickly off then on while going straight. Sometimes the problem goes away for a couple miles or a couple hours. I drive 2 hrs round trip a day and I'm able to still get their. So I took apart the throttle body assembly and cleaned and installed back on. I noticed that it ran further when only pressing the gas pedal the slightest amount to get the best thing acceleration. A few days later the same problem returned. I thought it worked better when I cleaned it so I removed it again. I noticed alittle bit of oil inside the tps so I cleaned and decided to clean the pcv box thinking it was clogged and was pushing oil back up into the throttle body. Glad I did it was completely clogged. Cleaned and installed a new one and reassembled it back together. Mind you from the first reduce engine performance problem the cars cel was present but everythme I would turn the car off it cleared the codes. So it's been three days now and everytime I turn the vehicle on the cel is displayed followed with weird idling, purging, shuttering, and dieing. I was finally able the scan for codes and got some code. P2177, p0507, p2187, p2135, p0121, p0221, p2177, p0507, p2187, p0102. I desperately need my car for transportation and I don't have the money for a shop. I'm fairly good at fixing things myself. Please help me figure out what's wrong with my car.

 

If those are throttle related codes - are you aware of the problems with the throttle body harness, and the replacement parts available to solve the bad connections?

Thanks for replying. No Im completely scrabbling to get it fixed. Everything I've read online and through the forums that pertained to my cars issues where never concluded. Seems like everybody weather they took it to the dealer the got charged alot of money and they still had the problem left with throwing money hoping to fix the car.
I don't have that option. I figure I can from buy a new throttle body and or throttle position pedal sensor and hope for the best without having to even go into ecm discussion.
Why can't I just buy a throttle body sensor without the body. Switch them out. Instead of buying the whole thing like the majority of other throttle body as a kit.?
I'm stressed out. Earlier today there was no response from my pedal at all for awhile even after turning car off for a min.
Wouldnt that be the pedal sensor not the throttle position sensor is the car was reving up and down with the pedal to the floor.. I have not even went home yet and I live a hour away. Then I have to come back tomorrow morning. There's no diy backwood hack that I can do to buy me some time with what I have currently. Or just keep driving unil what? What will happen if I keep driving it in its condition? Please and thank you for your time.
