Hi I have a 1999 toyota camry LE 4cyl, I have a short ram intake and I notice once I get to about 70mph and I floor it, the rpms jump up to about 4000 and it just seems to hesitate and the tach will actually jump down a few hundred rpms to about 3800 (all while pushing down 100% on the gas pedal). I just had my 90k service done on the car including timing belt and it seemed to help a little and the rpms dont jump down quite as much but it still happens and makes for a hard time passing on the freeway. I had the service done at the toyota dealership and they pretty much looked over every engine component as part of the 90k service and said everything is perfect. So I was wondering would the short ram intake be causing the problems at higher speeds? The car runs perfect, gets good gas mileage, and runs perfect at lower speeds.
