Im going crazy. When I got the car the car had a miss ( I dont want to call it a miss. It just feels like a spark plug problem) The only thing is that I have changed the plugs, wires , rotor as well as the cap. They told me I could be the TPS sensor I changed it and still the samething. I had a code 22 and a code 13 and after I changed the plugs I removed the ground from the battery and all the codes were cleared. But I still have the same problem. I also added a fuel treatment to the tank to see if that was it but as you all now that was not it. Please give me a help full hint so I wont go to my last resource. (0.10 cents of gas and a lighter) Just kiding.

 

I am not the best shade-tree-mechanic but I see that no one is responding to your post, so here is my guess...

I'm wondering if it is an injector problem due to the fact that it only occurs when you let up on the gas. One (or more) of them may be somewhat clogged and/or not working correctly.

I don't know how to test for a clogged injector.

However, you can test the injectors to see if they are electrically correct.

With the car off, unplug an injectors electrical connection and test the 2 prongs (on the injector top) for resistence with an ohm meter. Write down the reading and plug the injector back in. Repeat for the remaining injectors.

All the injector reading should be pretty close. However, if you find that some are far apart, then something is wrong with them.

I did this on my 89 a few years ago and ended up replacing all 8 injectors.

Hopefully, some nice forum member can tell you how to determine if your injectors are clogged

Hope this helps.

Best of luck!

 

Thanks for the info....

 

Do you know what the trouble codes mean?


13. Oxygen sensor signal stays lean during warm engine cruise

22. Low voltage at throttle positon sensor OR
Fuel cutoff relay circuit open or shorted to ground



An O2 sensor is like $20, replace that if you haven't. They should be changed every 30K anyway.

 

Thanks for your input.
