2000 kia sportage ex won't idle

Two days after passing CA smog test, I turned on the A/C in my sportage and it didn't seem to do anything. Then suddenly I lost power, it began idling erratically and within a couple of miles completely died. Had it towed home and checked the engine codes. It shows codes 326 and 300, 301, 302, 303, & 304. We replaced the Knock sensor (code 326) but nothing changed. It still won't idle and backfires sporadically. It will start but not without constantly tapping gas pedal. If I get the rpms up high enough to keep it running, I still have to play with the gas pedal to keep it running. For example: If I get it up to between 3000 & 4000 rpms it won't stay there, it fluctuates wildly then dies. Any ideas? Already replaced MAFS & Knock sensors, spark plugs are brand new, leads are fine.

Need a repair shop to diagnose it

You never should have thrown one part at it.

That is a Wish & Hope-- Push & Poke Diagnostic Theory,
that only takes your money & you replace every part,none
of them being tested or bad

SOURCE: 2000 kia sportage ex, 4 cyl.

Yes there is a sensor that controls Fuel/air ratio.It's called a MAF (mass air flow sensor)
But I think you should have the EGR (Exhaust gas recirculation)valve checked
and The TPS (throttle position sensor)maybe dirty.

Although may things can cause this issue,I would look at the items above first.

SOURCE: 2000 kia sportage. no start no spark no injector pulse.

check both of your fuse panels for a blown fuse. there's 4-5 that control the fuel pump, engine sensors, fuel injectors and such. one of those may be blown and not letting the rest of the system function. one panel is located under hood, and one is under the dash on drivers side. when you take the covers off they have the fuses numbered and tell what they control.

SOURCE: 2000 kia sephia constant engine stalling!!!

try this procedure and let me know if it cures the problem.

Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

SOURCE: 2004 Kia Optima no start after timing belt, crank, cam sensor replacement

did you use aftermarket crank sensor? if so that might be your problem. dealer has several different ones, by providing vin number, but there is only one after market for all optimas 01-05. try to connect thick pink wire and thick orange wire together on the ignition failure sensor. you might have the same problem as me. good luck.

Won't pass smog when it should...


Just because the car seems to run well, does not mean the emissions are within spec. For example, you could be running a little rich and the car will start and run great, but the exhaust is not within code.
What you can do is take it to a "smog shop", that is a repair shop with the proper equipment to diagnose the problem. If the testing is simply the reading of the on board computer codes, then most any place can read those, but you need an experinced mech to know what to do about it. May need an exhaust gas analyzer to physically sample and analyse the gasses. For the actual test, as long as the computer says all is fine, usually, you're good to go.
If the computer looses power any saved run data will be lost and must be re-accumulated to pass the smog test. A few hours to a day is usually enough run time to accumulate enough data.

No any codes will let you fail..Rangers are bad about the valve sticking..But first look on th driverside very back on the intake..Youll see a valve with two vacuum lines The one that goes on the bottom of the valve makes a 90 bend and is bad about breaking..If the lines are good then work the valve by hand and see if it will move

My 1994 Toyota pickup is showing code 25, and I am passed due for my CA smog test. How can I get my truck to pass smog?


The code 25 is an O2 sesnor code lean condition, the problem is usually not the sensor but another problem, it can be caused by an engine misfire, if that's the case the cause for the misfire has to be corrected first.

Will an engine bought from a 1999 Silverado originally sold outside of California pass California emissions


There are two type of emission classes.

Federal and California emissions.

Look under the hood for the emission class sticker.
Smog check station's machine in CA are programmed to handle both types.

You do not need to change anything before the inspection.

==== Side notes: You should check the service record for the last Catalytic converter,O2 sensors and EGR valve change.
Service interval for
Catalytic ~180,000 miles O2 ~150,000 miles EGR ~160,000 miles


If you can locate the last smog test (even from out of state) Check for the
CO NOx

I have an 88 VDP. Recently tuned up in AZ with new fuel filter. Always passed smog tests with flying colors. Last test in '99. Now in CA failed as Gross Poluter for NOX. No EGR on this vehicle. Wondering...


Not sure the car can pass nox without egr. Why did you bring it to CA? A draw on the battery would not affect the smog test. What you would need to do is buy the intake and exhaust manifolds with egr ports and also the computer and wiring harness that will make the egr system work. Not worth the effort unless you are in love with this car.

SMOG TEST


If it was originally intended for Texas, it's probably been made as a 49-state-compliant vehicle (CA has stricter emissions). To pass in CA, you may need some new parts for the truck in order to get it to pass. Or you may find that the best course of action is to sell the truck and buy a CA-emissions car.

The CA DMV may well have information available on how to get non-CA-compliant cars to pass the CA emissions testing.
