You could have a Air Idle Control valve or sensor problem. Your going to have to scan the ECM to find out if it is your (IAC).
Here is how to check your ECM for Codes. 
On board diagnostic (OBD) was designed on vehicles equipped with electronic fuel injection so you can generally retrieve the codes yourself. No need buying a scanner or running to any parts stores to check th3 Engine Light. This system is called obd1 and applies to most vehicles made before 1995 for domestics and 1993 on imports. In this article, I will discuss the methods used by domestic vehicle manufacturers on how to check the engine lights in their cars and trucks.
For GM domestic vehicles made before 1995, the diagnostic connector is located under the dash panel by the driver side. To get the check engine codes to flash in your dash panel, use a jumper wire or a paper clip and connect terminals A and B of the diagnostic connector. Turn your ignition key on with engine off and the codes should start to blink. All codes should start with code 12 which is one long flash followed by 2 short flashes. This code 12 means the diagnostic system is normal and will repeat itself continuously if there are no trouble codes. Otherwise, code 12 will flash 3 times before flashing the fault codes.
The codes can be erased or cleared by disconnecting the battery negative terminal for 1 minute and reconnect. Just make sure to check your service manual in case you have electronic equipment such as radio or clock that needs reprogramming in which battery disconnection is not recommended. Finally after performing repairs on the culprit code, always go for a road test to confirm if the problem is fixed.
Good Luck and here is a link for gm codes.http://chevythunder.com/199295_lt1_trouble_codes.htm#Code

If this engine is a VORTEC then you may have a problem with the internal fuel system. Under the top plenum there is a fuel reg and poppet valves that inject fuel into the cylinders. Sometimes the tubes that run fuel from the reg to the valves can leak and cause your problem. This cannot be found with pressure check because this occurrs after the reg. PS fuel mileage will go down. Let me know if this helps.Moe

sounds like you have either a bad sensor, or maybe a vacuum leak. is your check engine light on? if so, then try to have somebody plug in a code reader to find the trouble codes, and that will be a very good starting point. repost the information that you get, and well be able to help you out a little better. if there is no check engine light, then you most likely have a vacuum leak. maybe a cracked hose, or a hose that came off of its fitting? its time consuming, but a visual inspection of all of the vacuum lines is the best way to find this problem,without having to take your truck to a mechanic.

2000 Suzuki Esteem 1.8L.. I went to start my motor & turned it off right before started. I heard some kind of backfire. Then I started it and it's been idling high, the surging. Please help!!


scan it yet, a FULL OBD2 scan? why not?if not.
now is the time...


the 1.8L J18 engine, same as the older Sidekick sports used.
same engine , know it I do.
its the precursor to the J20, (j18 is under-stroked, j20 with many of the same parts. inside)
the back fire means explosion sound to rear end of tail pipe?
yes, that is rich raw fuel in the muffler. plus Air.
if there are exhaust cracks and then engine goes rich this can happen( a double failure)
if how ever BACK means, back to the Air cleaner, then that be different reasons, (timing)


engine now starts.?>
engine runs.? has full power, car drives ok.?
JUST?
SURGE,. you never said.

does engine get hot? 180F or more and holds (y/n)
ever get a full tuneup this decade,
most dont so i tell you, bad spark causes, misfire and raw fuel is wasted to the exhaust and sure can go boom.

surging usually means the ISC can not control idle
so it hunts, (a suzuki software engine on all 90s engines)
PCM errors, inside it. (dangerous too)
a modern car, if idle goes too high the ecu commands the ISC closed
and holds it there solid, (safe way , no hunting allowed now)]
so if this car surges, it's , lean engine.

some think flooding is surging.
and this is usually below 800 rpm,
almost stalls, then corrects, seems like a surge.

next time post rpm range of surge.?????

do not drive a surging engine, do not be like Toyota drivers. (over 800 rpm hot)

surge from 400 -800 rpm is class 1 surge.
surge from 800 to say 2000 RPM is class2, and very dangerous to some folks, (key off, get car fixed, tow it)

The ECU controls idle speeds. (hard coded servo controls)

While driving my jeep seems to be shifting gears the rpms rev up and then goes back down almost as if surging I changed speed sensor as a guess so far but did not work?


old 1995
we need vastly more symptoms then that,sorry
if the engine surges, that is first. (surges in 1 gear)
but if a transmission down shifts that is normal, rpm rises
(after all its a lower gear) (higher numeric ratio)
find any machanic in town
ask him test drive it.!
10 min.later he wilt tell you
its trans issues.
or its engine, super easy this is driving.

seems you can not, and learning is 1hour in car class..or 10x that lacking facts of drive train functions.


stop guessing. why spend cash on a useless sensor now.
spend cash on $1 shop diagnosis and WIN.
i promise !

or get it scanned.
and post all those DTC errors. P0700? and more.

It sounds like your clutch is slipping. Does it do it more when the wagon is loaded or going uphill?
Most likely needs a new clutch.

Engine surges at rpm over 1500


Look for a vacuum leak (lines and intake), Is the engine light on, were any codes present? A faulty EGR or IAC could cause the problem too. Check the throttle cable for any restrictions.
