hello Pals,

I just bought a 98 C280 with 165,000km last month, the condition was good until after oil exchanged last week that garage cleaned my airfilter (high-flow), I browsed the internet says that the MAF is easy to get dead if you are using a high-flow filter, I admit to it, but I doubt the meter was dead because the idle speed was in normal condition (+/-600 rpm), and the engine is easy to strat up, the only problem I met 3 days ago was on the high way, at the first everything was ok, kick-down was fine, but after I down the exit for 10-20 min on the crowed road, my car didn't feel like to move even I heavy stepped on the padal, it just didn't move a lot! seemed like I can only drive with gear 3rd, the car moved slowly! then I stoped the car, turned off the key, then started again, then the car was back! what happened?? the garage people told me that MAF was 100% dead, then they diaged my car with computer, everything was fine, all passed! I am wondering the MAF is dead, could it be the fuel pump problem?? it would be apprecite to get helped here.

 

anyone can help?? it has been happened once so far, but i am afraid it suddenly stopped on the highway,,,,
