Question Hi my brother has a 91 camaro rs 3.1L v6 a month ago it started well and ran good about a week or two ago it started up but when u press the gas it would start to bog and the idle would be peaking at 2-3,ooo rpm but it will not accelerate at all he replaced the fuel filter and pump changed out the IAC,FPR, and the mass air sensor,TPS but still acts the same it feels as though it might not be getting enough air the throttle body is sucking air but when revved loses it and starts to die if u could figure it out that would be very helpful
Answer Hi Adam... check for plugged exhaust or cat converter.... just undo exhaust at the manifolds and run the engine, if it runs ok then the exhaust is where your problem lies.if that doesn't solve it then the only other thing that comes to mind is an intake leak....take a can of air intake cleaner and spray around the intake listening for an increase in rpm. if you get any then you may need to re and re intake and install new gaskets...this is a common problem with those 3.1 L engines....check for vacum leaks and collasped vacum hoses as well....hope this helps
