Newbie to the forum and in need of any help. I am the proud owner of an 89 190e 2.6. Having problems with warm starts. The car starts fine when cold. When its hot and I shut it off, it will start fine unless i let it sit any more than 10 to 15 minutes. In which case it will take about 7 to 10 times of starting and stalling before it starts, huffs and puffs for about 5 to 10 seconds, clears up and once again runs fine. Almost like its choking itself out or something. I recently gave it a complete tune up and changed the coolant temp sensor. Im really racking my brain on this one. Any expertise would be extremely appreciated.
