Car is running rich, so decided to adjust the TPS sensor to see if it fixes the problem. My plan was to change the oil first before starting it up since the oil smells like fuel. The only thing is, according to what I've researched, I need to warm the engine up to set iac before setting the tps. The thing that sucks though is while warming it up during my rich condition, I'll be contaminating the fresh oil again. Can I just adjust the tps to get it close enough without needing to start it for the iac adjustment? I'm hoping the tps adjustment alone (with out iac adjustment) will at least get me in the ballpark so it isn't running so rich when I start it. Any thoughts? Thanks, Tim
