97 Cav= engine surging
Saturday, December 31, 2005 10:46 AM
Need to get my daughyer's car fixed. the engine cuts out at about 2500-3000rpms. the injector signal is being cut. I think i have a malfuntion of the rev limiter switch. where is it? is a replacement available at a good auto parts store? Help, Allen

Its software based, there is no switch. The ECU limits it when it see's the correct number of RPM's. How are you determining that its cutting out? Revving it in neutral or driving it?

Sounds to me like it could be a clogged fuel filter and the engine is starving for fuel once it gets to higher RPMs.

right now, i have been trying to solve the problem off the road. this problem also persists on the road.

I was told that the car does have a switch and there are known problems. I am pretty good automotive wise- but im not a GM nut. Allen

thought so at first but- New filter & pump- double checked the pump- the fuel injectors are getting cut out. caught that w/a VOM. Allen
