Hey guys just checked out an s2k and prty much confirmed the purchase. Im going to check it out again on saturday and do a test drive and use an obd2. But when i checked it out today I pressed the clutch in when it was idle and it started revving up and down from 1-2k for a min or two after i let go of the clutch. Ive heard it could be due to a dirty idle air control valve, but it happened when the car started from prty much a cold start. Any thoughts? Is it a big deal? Or just a quick clean. The owner said he hasnt experienced that bc he doesnt usually idle it for long before heading out. Isnt that not good? I also took a look at the coolant and it seemed like there was no liquid in there in between the min and max line. I did not open the cap to check so I might check it on saturday. Thank you in advance! Just trying to make sure I am making the right purchase.

 

Immediately driving off after a cold start is perfectly fine as long as you don't let the revs/load get too high while the engine is still warming up.

 

Sounds like there is a vacuum leak on the intake manifold / throttle body system. No self-respecting S2000 owner would let their overflow tank run dry, if it is dry no telling what else was let go. I would check the rad to make sure it is at least full.

 

it did only happen when i pushed the clutch in and released. Not sure if that makes a difference. Everything else looked good but will need to double check the coolant.

 

if i use an obd2 reader and everything checks out should i be okay? After i check everything in the engine ofc. There were no leaks or anything like that.

 

To help you assess the car we need a LOT more information. What MY? How many miles? Prior use history? Modifications? Accidents? Body panel numbers present? Condition of top? Repair history? Pictures would be a big help, including the engine bay and the undercarriage if possible.

 

yea its got 116k miles, all stock, sparkplugs changed at 100k. One owner. Maintenance done by him.

 

clean title no accidents
