if its doing it by itself, try replacing egr valves. the engine is adapting to how much fuel its receiving. if the engine revs very low gas it slightly for about 5-10 seconds and it shoudl stay level for a bit Answer It's the air idle control servo, not an egr valve, you can just take that off and plug the hole in the intake with a bolt and it won't do ne thing, but the air idle control servo is either bad or is dirty where it seats into the throttle body, it's a very common problem with the eclipse talon and laser, only other thing that could cause an idle surge is the tps or throttle position sensor, but if that was bad the car would be runnin bad, good luck and be careful about the answers you get from here cause I personally wouldn't use this forum for good answers, if you want real good info on your dsm, go to dsmtuners.com, you'll get trustworthy answers there
You need to turn off the Overdrive switch.
Turn the throttle, revs go up. Let to, revs go down.
No. The 1995-1998 Talon body style is completely different than that of a 1994. If you try this, the 1995 will be about three inches wider and one inch taller, and none of the screws will match up.
My talon tsi is still at 150,000 and still runnign strong, proubably 300,000 if you keep it up to date
There are several reasons why your car may be overheating. Check the thermostat to be sure it isn't stuck. If the car revs up and down, the timing may need to be adjusted.
it might be your jets
Try servicing the air filter.
I just had to do this in order to replace my water pump. If you're not mechanically inclined I'd strongly suggest you have someone certified set the timing. Since then my 91 talon revs up and down as long as it's running. I just bought an Idle Control Valve. I hope this will fix the surging. There are notches, or timing marks located on the sprockets that have to be accurately lined up in order to set the timing. hope this helps.
Check the craigs list listings in your area. Look it up on google
When mowing it will idle up and down because of the amount and thickness of grass you are cutting. This is because the blades will struggle cutting thick grass so the engine needs more revs to keep the blades running at a constant speed and that is also why your mower may slow down because it has used the majority of revs to cut the grass and their are not many revs left to keep the wheels spinning The up and down revving could also be caused by a dirty/clogged air filter.
Jack it up under the A frame on the side you are working on.
Check your radiator is full
