GP's affect cold starting. Valves, when they first become too tight, also only affect cold starting. (If they get tight enough it'll affect running, and can result in burned valves.) GP's, the parallel kind, should measure about 0.7 ohms when cold. It's easy to do from the GP relay plug. You need a decent meter that can reliably read sub-ohm values.
These are both good tests/adjustments to do on any new-to-you vehicle. Also look for fuel leaks, dirty filters, etc. -- Jim _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
