BMW: 84 bmw running rough, bmw car club, bmw car club of america

Question
Josh   Well....I dont know where to start other than thanking you for all your help with my sons car. The first time after he brought it we had to have the clutch replaced and everything went down hill from there. But if it wasnt for you it wouldnt be running right today (with out emptying dads bank account) First of all I checked everything you told me about the car and the main thing was the coil(supprised me) after following your advice on everything else I did end up replacing the IAC valve and it dropped the idle from 3500 to 2000 rpms but still wasnt right. then I went back again over everything and .....found the temp sensor to be bad upon replacing it everything started working just fine were finally running at the factory settings and im happy as all get out. If it wasnt for you I believe it would have cost me an arm and a leg in repairs with the BMW repair shop we have here(they couldnt even catch that the coil was bad). So once again Josh I really appreciate your time and effort you are a life saver.      Tom

Answer
Tom,
 Hey, thanks alot for the kind words, it gives me much satisfaction knowing I helped you guys learn about the car and save money.
 I'll give you a few tips for the future....  

 If you buy parts from a dealership much (I hope you dont) then you can become a member of the BMWCCA (BMW car club of america) and you will (or should) get discounts on parts from the dealership.  This has saved a load of money for me on stuff that can only be bought at dealerships.  You will also get a great monthy catalog, and discounts to BMW trackdays and first dibs to good seats at races.  (Got to see a McLaren F1 with this club!)

 Also buy from Bavarian auto (I think you mentioned this)
 www.bavauto.com

 and: www.pelicanparts.com

 Some good info can be found on:

 www.e30tech.com (mainly for guys modifying these cars,  but some good tech stuff too).
 www.bmw30.net (mostly tech answers and stuff)

 Glad I could be of assistance, and your questions are always welcome.

 Take care,
 Josh
