1998 TAHOE HOW TO TEST A CATALYTIC CONVERTER
If converter is cloged engine will have hard time getting rid of hot exhaust gasses and will have no power if it runs at all. Check for the gas that comes out - when you nail the engine lots of gas should come out - if it does not amount to much it is obstructing the flow of gasses and needs to be replaced.
My 1998 chevy Tahoe won't shift gear.
Can you give a lot more detail Priscilla., add it and then resubmit the query. Do you mean it will no go into gear at all? Will the gear selector move but no dear engage. (if this is the case first check that the tail lights are working, they must for gears to engage in US automatic cars apparently.)
It might be that the gear selector is broken or the torque convertor
has collapsed . Try the tail lights first, you c can fix those yourself /
Why wont my 98 chevy tahoe start
Either it is not getting fuel into the cylinders OR the spark plugs are not firing. Could be defective ignition switch, blown fuse to the fuel pump, blown fuse to the ignition, bad connection somewhere, you failed to pay for your permit to drive from the Homeland Security Bureau
My 1998 Chevy Tahoe shakes real bad about 50 60 miles per hour and stopped at my 75 what's the problem
Jason, it can be a number of things causing the vibration..check the obvious first like Glenn Blevins answer. If that doesn't help then go on to the less obvious things..Like...
Hard starting or getting real bad gas mileage? (I know, the mileage sucks to begin with..I own a 2000 OBS Tahoe Limited so I know the mileage sucks!)
*Fuel pressure regulator..
*Spider fuel injection..Check these to make sure pressure is holding good.
*Distributor..They wear and act crazy...I'm in the process of changing mine now...It made my Hoe shake badly!
I don't know what the mileage is on your Hoe but I would say it's about time to start checking all the things I have mentioned.
There are lots of really good forums to get info on these trucks..OBS (Old Body Style) trucks have a large cult following so you will not be at a loss for info.
The vibration started at about 40 mph and would chill out around 65 mph...I knew it wasn't tires/rims on mine so I hit the forums and found a new world of info and testing to do on mine.
If it turns out to be a worn distributor on yours, go to ebay and purchase an billet aluminum made one..about 5-10 dollars more than the stock plastic shell OEM one that came on the truck.
Security light remains on
This happens when the ignition can't read the key. If it is not starting when it does this. to fix this leave the key in the on position not running for 10 min or till the security key flashes and turn it off wait 5 seconds and then start it. If the light stays on and it is running just drive it like that put some electrical tape over the light. ours has bin on for 84,000 km and this no start thing has happened a few times this is a common gm problem. hope this helps you.
