A good smog tech in Calif. would of caught the no CEL and not passed the visual inspection test. Don't know how it is in Texas. If you find the bulb is good its time to follow the trouble tree in the FSM, I believe its in section 8a index.

Thanks, I read a thread where I think they found a faulty speed sensor, screwed up idle, stopped the cruise and secondaries from working. I will get on the check engine light fix. The smog tech didn't catch it thankfully! Since they didn't move the car during the smog test, the speed sensor works great when not moving! They did drive it around the building to check brakes etc. This is probably the first thread where no check engine light is a problem!

Thats a good 1, it was the 181.3 MPH pass, Bill & Greg loved it that that blew it out, I went too fast for it to handle, Life begins at 180 except for speed sensor

Update: Been working on the car this afternoon and found some bulbs had been removed. Luckily the missing bulbs were sitting below the information panel behind the bezel. I used a flash light to see which of empty holes had something to display and needed a bulb. The check engine light now works as well as the service suspension light. The weird thing now is that the suspension now adjusts! finally a good firm ride. The check engine light stays on but now I can get the codes. The low coolant light is also on but not low on coolant. As soon as I started driving it the check suspension light went out and adjusted properly. There is one more light on but my bad eyes had a hard time reading it. Looked like NFL RIEST??? What does this mean? I don't have an owners manual and my FSM is missing the first few pages (table of contents) and the last few pages of the index. Makes looking things up really challenging!

INFL REIST is the air bag system not working. I think, if I remember correct that some systems will not function if that light shows a code,[ie: cruise control]. 90's had a service builetin about bad frame grounds at the sensors, think 91's had a updated system. Try disconnecting the ground side of the battery for 15+ seconds to clear some codes. See what comes back as a hard code. Then use the trouble tree for that code to attempt a repair.

Correct me if I'm wrong - but I'm thinkin Marc told me another cause of high idle is a clogged MAP sensor hose? As in if there is a sag or low spot in the hose the oil can collect there and block it? I know he changed the one on mine and told me that was an issue with these cars...
I CAN tell you that mine idled way high and slowly worked it's way down when you stopped at a light before I had Marc work on it. He changed injectors, coils, MAP hose, fixed one of the secondary actuators, and fixed a few vac hoses. I also had him put his chip in it... Idles like a champ now!

I pulled the stored codes and Have:
14 and 66 Is this coolant low and a/c low pressure? My low coolant light is on (Will have to check wiring and sensor) and my a/c system is empty but will convert to R134 as soon as I locate the orifice and replace with a variable orifice. Also would like to get that INFL REIST light off.
