92 DX RUNS BAD ONLY IN RAIN please help

[xmsleepR]

Im noticing the same problem funny part is that it was AFTER doing a whole tune-up..

btw autozone pulls the codes out of our OBD1?

Actually I haven't taken my cb to them but I took my celica as far as I can remember. It was a 1992. Maybe they can't. I haven't ever had any problems out of mine until now but it's nothing to do with throwing codes.

yeah im not 100% sure they can scan it to see what the CEL is if the CEL isnt on ya know, it came on but went back off, its been a few days and it hasnt come back on and it seems to be cleared up some, but im sure that as soon as it rains it will be right back to normal...or....ab-normal i guess.

They only scan OBD-2 cars at autozone. Your cb is OBD-1.

Luckly the cb7 is a self CEL reader.

If you look in the passenger side kickpannel on the right, there is a blue connector. You bridge the two pins with a wire or paperclip then turn the car to "on"

The CEL will start to flash. You read it like this, long flash= 10s short=1s. so a long, long, short would be a code 21.

There is a list of the codes on this site, use the search to find it.

do i have to do this while the check engine light is already on, because as soon as i shut the car off...it goes away. just wondering if it will still read the code with a non-active CEL. does that make any sense??

you can check the CEL with the car on...just jump the service connector and the CEL will start flashing
