I have a 98 Boxster with 19,000 miles. I was driving the other day and I encountered a problem. When I wuold step on the gas peddle to go faster, the car would hesitate and bog down. At times I could not accelerate above 50 mph. I did put in Techron thinking that it may be an injector. However, the check engine light eventually came on. The car is now at the dealers and he tells me it may be the air mass sensor. Does anyone have any info about this and the possible cost to fix it. The dealer has not yet told me what the repair will cost. I am somwhat skeptical about this dealer but he his the only one in my area. Also, the SRS light has been on for a couple of months and he now says it is the seat belts. Is this worth fixing. This car is becoming a money pit. I am not sure if the seat belt issue needs to be resolved. Any suggestions?
