New old car

Hello, Probably old issue 1997 Supercharged 80k was sitting 10 years abs/traction control off illumunated on dash runs operates fine, small tear in the pass side outer cv boot.. runs fine at 1700rpm 58 Mph @ 2400 rpm speedo is 60mph seems like its going faster but just 60 on speedometer
I think somethings disconnected

My first guess is speed sensor-




The ACDelco is $50 on RockAuto, el crappo options are as cheap as $9; so this is not too bad if it is only the speed sensor.

Thanks for the input could this trip the traction control dash light/ ABS light?

Had it two weeks 1100 miles, its been cool how would you suggest i test my cooling fans? It seems to run under 200 degrees fuses are good will be charging the A/C this week

Short answer, I don't know, but I'll ramble a bit.  I don't think a bad speed sensor would trigger the traction control light.  Could you feel traction control kick in?  You can't miss it if it's happening.  It's sorta like going over speed bumps.

How is your brake fluid level? I had a problem a few years back that was caused by a brake fluid level sensor coming uncovered under acceleration, because the fluid level was too low. I don't remember which warning light it set off, but it could have been the traction control light.

What makes you think there's a problem with the fans?

Thank you, trying to just stay ahead of whats comming so far its been fun, got this to escape
Sensor issues on my 2014 impala, i can work on
This or take it to a low tech garage not like going to the dealer and having to reflash $500 bucks lighter
I dont have abs or traction lock function but have all summer to figure it out

I'd recommend getting a set of the factory service manuals off eBay.  I don't have any experience with these problems, I'm just looking at my copy of the FSM for answers.  I'd look at the sensors for ABS and traction control as well.  It's possible all these sensors feed into a computer module that is bad, but I think it's more likely the sensors have gone bad.  So far I've replaced the crankshaft position sensor and the camshaft position sensor, and deleted the O2 sensor on the catalytic convertor.  Just part of owning a 90's car.

Ok so where is the high side a/c port? In a 97? Please

You should find a 'measured mile (interstate highway mile markers) and time yourself going a mile. 2400RPM at 60 MPH ust sounds like the transmission is stuck in 3rd.

Put it to you this way: Your car's been sitting *10 years* and is bound to have a number of issues. I agree that you need to get a factory manual set; factory equivalent scan tool (not just a code reader) will help as well. Because using that you can read the sensor inputs directly and figure out whether or which is lying to you.

In lock up OD, RPM should be approximately 1600 RPM@ 60 MPH.  The Riv has a really tall final drive, about 2.06:1.  Should shift into OD at around 45 MPH, light throttle.  Can you feel it?

Thanks, i now have A/c after puting about 11 ounces in it the control on the pass door panel lit up is that what controls the blend door? Drivers side
62 degrees pass side 45, i think it may be low still

The only way to know is to put a gauge set on it. Overcharge is just as bad. You can still have a blend door actuator problem. I don't know. I would think the passenger side control moves a blend door. Take the glove box door off, and have a look in there as you move the control.

Will do tks after talking with my budy who was measuring may have put 16 ounces in
