Sluggish Performance/Lack of Power/Low Idles

Hi All,

I've 73K on my car and was too cheap to take it to dealer for tune-up so did it myself. I have done on my Celica 2001 GT:

1. Replaced Air Filter
2. Replaced Spark Plugs
3. Adjusted Throttle
4. Cleaned MAF and Throttle body 2 times with Air Intake Cleaner
5. Changed Transmission Fluid
6. Flushed Coolant and Power Steering Fluid.
7. Bottle of Fuel Injector
8. Replaced pcv valve
9. Replaced Drive Belt with Gatorback Belt


It was running smooth for about a month and now I started noticing sluggish performace/lack of power when accelerating and also low idles (400-500) when coming to a stop. I've spend 2 days researching problem on different forums but haven't found anything. Could it be the Gatorback belt (last thing I replaced on my celica) or MAF that's causing this? Pls help.

I would clean the MAF again and clean your grounding points on the engine.

Hi All,

I cleaned MAF sensor but still same problem. Also use volt meter test and it's showing 2.05ohm. According the vol2 repair manual, it should be between 2.21-2.69ohm. Dooes this mean I've a bad MAF?

Thanks again!!!

Went to toyota dealer today and they wanted $139 for the MAF. Don't have the money for it yet so I will probably get it when I get pay next week. Is there an aftermarket MAF sensor for a Celica?

Thanks.

Did you use a Fluke meter or a high quality digital multimeter? We have to get our meters calibrated here at work. I was shocked to see how many meters are off! It should be easy to remoce the connector and check it again.
You have any friends that work on airplanes? Their meter will be calibrated.

Never heard of an aftermarket

Hi maingear,

NOt sure how to calibrate the digital multimeter but I can ask a friend at work. As for cleaning the grounding points on the engine, is there a cleaning product to use and also where is it located?

thanks again.

Try ispropal (spelled correctly?) alcohol.

(Isopropyl) i think

the meter has to be sent to a company to verify that the meter is correct, that's how it is calibrated.

It's like cleaning a battery post, just not as nasty. I like 3M scotch bright. I think it is by the S.O.S. pads in the cleaning section in stores. If anything metallic is used, the connection will corrode again. on airplanes, we use petroleum jelly to coat grounding straps before assembly, then after assembly to protect the parts from moisture, copper antiseize can be used also(like what is put on a lawnmower spark plug). (Two different molecules cannot occupy the same space, so it acts as a barrier)

Some guys at work have coated their ground connections with RTV, to later find that it held moisture in, and made the problem worse.

If you look in the third Pic you can see two of the ground wires (They are white)
