This is what my Jb mech does. No agaration or trial and error That is trial and error. Change parts and test result. If no good, change another part and try again. ↡ Advertisement Link to post Share on other sites More sharing options...

They order new part and if its not the problem, you still paid Some local workshops do have used parts. Sometimes they strip cars before scrapping (for those who send to them to handle) and keep working parts. However, they may not necessary give you new parts but still charge you new, especially for stuff you can't see. How many customers asked for old parts back to prove parts have been changed ? Ultimately, it's the integrity of the workshop boss. Link to post Share on other sites More sharing options...

Thanks bro Jerking and rpm not stable - is this during idling ? If so, your engine idling air passage is either dirty (if you have poor filtration aftermarket air filter) or the IACV motor is not working properly.
