New guy with a question

[jdubcee]

I'm new to the forum. I have a 1986 Olds 442. Been lurking for a few years. I was driving today on the highway and was driving around 75mph. When a car came up on me kind of fast. I put the pedal to the floor and my car made and terrible noise and started to sputter. I didn't have time to look at the tach but could this have possible been the rev limiter kicking in. It drove fine the rest of the day I just want to make sure I didn't mess anything up.

This car is a daily driver that is pretty much stock except a chip, and plugs wires and air filter previous owner installed.

I don't think older 80's FI had rev limiters. But I'm I'm not for sure.

If your car is stock, Im pretty sure that theres not a rev limiter. What speed were ya going and for how long? Sometimes, if you are going too fast for too long, you can actually use up the oil in the pan and the lack of oil pressure will cause the ignition to cut out as a safety measure to keep ya from burning up the motor.

I was traveling about 75 mph and push down on the pedal hard to accelerate it only lasted for a few seconds and car did speed up faster. I would guess I speed up to about 85 for about thirty seconds. That's what it seem like, like the ignition was trying to cut out.

check the plugs and wires, cap and rotor....sounds like it may need a tuneup or it may have a worn out distributor.

I will. That might explain the changing idle speeds sometimes as well. Thanks

Something else to consider is throwing that chip in the trash. These cars are not like the modern EFI cars and the chips do nothing more than advance your timing a little. That's it. And since they only do this at WOT when the CCC system goes into open loop, there's really nothing else for them to control.

I put one in my '87 back when I first started college and it did nothing more than drain my wallet. 🙁

As far as a rev limiter, these cars didn't have one stock. I remember with my 307 it had a natural rev limiter which was likely valve float at only 4000-4400rpm. :lol: It just would not pull past that rpm.

Yeah FE3X someone else told me the same thing about the chip. I have the stock chip is there anything special I would need to do or is it just plug and play. Thanks
