willsboattail Posted February 12, 2010 Report Share Posted February 12, 2010 I have a 1993 Cutlass Convertible with a 3.4L V6 DOHC engine in storage for the winter. Started it yesterday for a mid-winter warmup and revved it a few times after several minutes of running. Engine would not rev past 3000rpm. Pushing gas steady to get higher than 3000rpm, it began to rev cutting in/out, back/forth and didn't rev past 3000rpm. Is there a rev limiter on these things, or do I have a problem coming? I did not drive the car as it's snowed in the storage unit. Kevin in ND Quote Link to comment Share on other sites More sharing options...
Night Fury Posted February 12, 2010 Report Share Posted February 12, 2010 Yes, that's a rev limiter. Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted February 12, 2010 Report Share Posted February 12, 2010 That's the rev limiter.. Quote Link to comment Share on other sites More sharing options...
Crazy K Posted February 12, 2010 Report Share Posted February 12, 2010 at 3000 and not 4000? Quote Link to comment Share on other sites More sharing options...
oldscsc Posted February 12, 2010 Report Share Posted February 12, 2010 Put it in neutral, if it is fixed its just the rev limiter. And it should be at 4100 not 3000.. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted February 12, 2010 Report Share Posted February 12, 2010 depends on the stock chip. i have at least three 91-93 3.4 BINs that show a cutoff at 3000... normal. EDIT: the 3.1 cars are set to cut out at 4000 though... Quote Link to comment Share on other sites More sharing options...
Regal_GS_1989 Posted February 12, 2010 Report Share Posted February 12, 2010 It's normal. My cutlass used to be limited to 3000 RPM. My 89 Regal limits around 4000, and my 88 never had a limiter Quote Link to comment Share on other sites More sharing options...
oldscsc Posted February 12, 2010 Report Share Posted February 12, 2010 Maybe they were changed for the '94 model year? Interesting, my fault for the wrong info. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted February 12, 2010 Report Share Posted February 12, 2010 Maybe they were changed for the '94 model year? Interesting, my fault for the wrong info. 91-93 and 94-95 use different codemasks, so it is possible. Quote Link to comment Share on other sites More sharing options...

willsboattail Posted February 13, 2010 Author Report Share Posted February 13, 2010 why rev it in park anyway? DUNNO...... guess I just wanted to create a bit more heat at 14 degrees above zero and warm it up faster. Maybe the poor thing wanted to feel a bit more macho sitting next to my 72 Biuck Riviera 455?

Not sure Robert. I just remember it cutting at 3,000rpms. 3.1 MPFI/4T60-E in the car. Stock memcal. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted February 13, 2010 Report Share Posted February 13, 2010 oh well, off topic anyway. important thing is that it's something adjustable if need be and that it looks like it can vary within the same mask and engine and still be normal.

Thanks for the advice and I agree. After owning 15 cars in my 53 years of life, I haven't dropped an engine, or tranny since high school back in the early 1970's!!!
