January 19, 201016 yr A little odd I suppose but here's the situation... Lately I have bveen starting the car (88 GL - EA82, 4WD, 3AT) and I get a check engine light. Seems to idle around 1500 or so off of a cold start (seems a little low). When the CEL is on, it's running a little rough when driving. Pushing the pedal at this point will only gradually increase RPM...not the super boost I am used to. The CEL is going away after about 5 minutes of driving. When the CEL is gone, it runs like a champ. I popped open the cover to the ECU and I get 7 short flashes when I turn the key to 'on' (not ignition)...which means there are no stored codes..correct? I know she needs a tune up soon...the plugs suck. Any one have any quick suggestions on what to check? The issue is intermittent, so I would guess some sensor wiring or something along that line (CTS, TPS, IAC...). Thanks a bunch!

The issue is intermittent, so I would guess some sensor wiring or something along that line (CTS, TPS, IAC...). Thanks a bunch! 7 blinks means no current code is active, which, when the car isn't driving.....means very few possible codes. What you need to do is plug in the 2 white read memory connectors. This will output stored codes. You may get several at first. I suggest recording them, clearing them, then retesting after a short drive. (clear codes by plugging in both green and white connectors, then rev over 2k rpm and drive 1 mph) light will flash when cleared.
January 29, 201016 yr Author I finally caught the light coming on so instead of doing the read memory procedure, I just turned the car off and checked the code...sure enough it was 31 - so I popped the hood and wiggled the TPS connection (the throttle sensor). Ha ha...The code hasn't come back. I fear taking that sensor off to clean it for two reasons: 1. I don't know the best way to preserve the little metal clip that keeps the sensor tconnector ight...I always end up bending the metal making the clip useless. 2. What is the best contact cleaner to use on those parts?
