Hi guys,
The car is '94 Aero upgraded ECU to ST5. The car runs fine for years.
The car had head p&p and upgraded maptun intercooler just last month.
Recently, I have found problem when I WOT and the engine would not rev
above ~5500, shift to next gear, the car goes well.
From what it drives, the car pull very nice from 3- 5 k rpm, a lot of wheel spin in 2nd.
Just when it hit sth. 5500-5600 rpm the engine won't rev more.
When in idle I could rev the car to fuel cut at 6500 rpm.
What is need to check at the moment?
TIA!
Craig
