Is the check engine light flashing, if so stop driving and figure it out, could have a cracked plug, or bad coil, these early trailblazers had an issue with the cylinder bore liners cracking and trashing the motor, try all new plugs and gap them correctly, .060 i believe, check the old ones for damage if found sell the car unless you want to replace the motor

check for moisture in the distributor cap if you have one. Check that the HT leads are not touching each other causing a misfire through the lead with no compression in the cylinder. Use lead separators to stop the leads touching

When driving in 5th gear should the RPMs run at 3000 RMPS. Mine is a 4 cly 5 speed


You don't provide much information to go on (type of vehicle, type of engine, 2wd or 4wd, etc.) RPM is always going to be based on the speed you're traveling with a standard transmission. My 4 cyl 5 speed Nissan pickup in 5th gear runs at 3000 RPM at about 75mph.

Lost power to engine


Check make sure all plugs are firing. Sounds like what my 93 Rodeo was doing-Idled okay but very rough when in gear. Turns out only 5 out of 6 plugs were firing due to a defective ignition module- 100 bucks later it works fine.

Hope this helps.

I was driving and lost power. All the warning lights went on, but the headlights and radio turned off. Engine ran for another 5 minutes.


Sounds like your alternator quit working or you may have broke a belt,the engine would stay running until you did'nt have enough power left to run the ignition system.

MY 2002 honda s2000 has a rough idle its missfiring on 3 and 4 cyl. i changed the plugs im thinking maybe its the coils any sugestions? is it safe to drive also


I would say the coil is most likly the problem if it runs 2 cly. and i would not drive it because of unburned fuel going into the cly's.
