is250 - tune-up
I have a 10' is250 with 105k miles. Besides oil change and air filter, I have not done anything else to the car. It seems to run well minus a PO303 code which didn't come back after a reset.
What are the recommendations for plugs? I'm thinking that I should also clean the throttle body and MAF. Any other suggestions?
Thanks in advance
Clean charcoal filter
Clean MAF - CRC Maf cleaner
Clean throttle body
New PCV valve
Spark plugs 60k intervals
Inspect serpentine belt
Idler pulleys
Power Steering Fluid (Joking)
Replace old brake fluid/bleeding
Reset ECU
All these DIY can be found using the search function here on CL, or Google.
