Going 65 mph my 91 (1.6l) sidekick rpm is at 4000 and at 75mph is at 4500 and about 80mph it is at 4800, is this normal or is something wrong? Please help!!!!
It's all about final the drive gear ratio. Sounds like you've got high 4's 0R 5 to (something) gearing. It's a lot of work to correct by adding lower ratio differential gearing. I'm assuming that your ride is a little low on horsepower from the factory, thus the high ratio gears to compensate. You COULD go with taller tires. That will lower the RPM at speed, but also throw off your speedometer and worsen acceleration at the same time. Speaking of such...are you sure that your speedo and tach are accurate now?!?
I run 3000 rpm at 70 MPH in my Zuki FWIW.

I'm with ya'! Just trying to help sort out that Lil' Sidekick issue.
He's probably got a higher RPM to engine power ratio than what I'm running to help compensate for his smaller engine. Either that, some significant "off road" gearing (factory OR modified).

My sidekick has a 5 speed manual, and it was bought from a owner in Wyoming so it could have been modified. Also after i rewired the plug to the injecter to get it running, (plug on harness was broke) now it smokes a little bit. Smells a little like fuel smell,so by useing starting fluid in it a couple of times, could i of fouled out the spark plugs? Or could it be something else? Thanks for the help!!!!

My 1995 Tracker, 1.6, 16v, 3 spd auto runs @ 3700 rpm @ 65 mph. Seems high compared to my 96 Sunfire w/4spd auto, but w/o overdrive I guess it's to be expected. Good luck, Dave
