fastamp;furious Posted September 26, 2005 Report Share Posted September 26, 2005 Are rev limiters standaed on this car? If i open it up from idle in neautral it cuts out at 4000 rpm. also the rough idle and miss seem to be in the 750-1000 rpm range then it smooths out. in earlier post i described a clogged cat issue. could the map sensor be the cause of the miss and clogged cat????. when I tested the map, the voltage , key on , engine not running , it was 3.8 volts(within specs) but when i started it up it was suppose to increase by 1.5 volts .it didnt... and when i went wot it was suppose to increase to apox 4.5 volts , it actually dropped to about 1 volt. and if i have a bad o2 sensor or map or clogged cat shouldnt it be throwing codes?

jeremy Posted September 27, 2005 Report Share Posted September 27, 2005 They have a 4,000 rev limiter in Neutral, but nothing in Park. IIRC: all of my w-bodys had a limiter in Park too .....you can have a bad or clogged cat with no codes Quote Link to comment Share on other sites More sharing options...
Kalgorn Posted September 27, 2005 Report Share Posted September 27, 2005 They have a 4,000 rev limiter in Neutral, but nothing in Park. Wrong. The limiter is in park AND neutral. Z34s have a limiter at 3000. Quote Link to comment Share on other sites More sharing options...
Vegeta Posted September 27, 2005 Report Share Posted September 27, 2005 Older cars (90 and back) didn't have rev limiters, and manuals don't have a limiter either (at least not till redline in some cases). THere is an in gear limiter, and a p/n limiter. Quote Link to comment Share on other sites More sharing options...
TeeJay3800 Posted September 27, 2005 Report Share Posted September 27, 2005 I didn't think I was wrong. I know I have revved mine past 4,000 in Park. Quote Link to comment Share on other sites More sharing options...
