1987 turbo coupe high idle Reply #16 – August 05, 2008, 11:05:25 PM Sometimes it is just best to GET UP GET OUT THERE AND DO IT! Codes aren't a guarantee they are there to give you and idea on witch circuit to look at. That by no means that if it says MAF is out of range that it is the MAF that is bad. What they are saying is that the MAF signal is not within spec according to the other sensors that they have info to compare it against. Why else could it tell you MAF and it turn out to be the TPS. Because the MAF reading was off according to the amount of of signal that it is getting from the TPS. So yes codes help A LOT! You still need to do some good ole checking to find out what is what before you just start dropping $$$ on parts. Why do I here so many times that the code said this and I replaced that part and now I still get the same Code. Because you use bought the part and didn't do the right thing and test to find out witch part in that circuit is really making that code come up. That is why, and that is why a real mechanic will find the problem and fixes it. The shade trees are the parts swappers. So what do you wanna be. Quote Selected
1987 turbo coupe high idle Reply #17 – August 06, 2008, 12:06:11 AM HERE HERE IPSD. That was a great explanation. I have been victimized too many times by being a parts swaper. I wright programming for a living and if ever I could be smart enough to right an engine manegment program, my fault program would tell you what is wrong. I seriosly think that these systems are designed to confuse so that you will buy the extra parts, stay confused and get a mechanic, or just go buy a new car. I try my best to wright my programs where no one else can read them. That away I have value to my employer. They think I am smart. With the help of these forums I am getting smarter. Although my car still runs like . lol Quote Selected
1987 turbo coupe high idle Reply #18 – August 09, 2008, 01:29:34 PM After finding a code reader,I got some codes from my 1987.15, 21, 22 and 14 were reported.It was wierd the codes went 15, 21, 22 15, 21, 33, 14, 14.I looked up the codes:14: Profile ignition pickup circuit failure15: Read only memory test failure21: ECT sensor faulty22: Barometric pressure/Map sensor faulty.Not to sound stupid, but I'm more worried about codes 21 and 22. What should I check to correct this problem? Any suggestions? Quote Selected

1987 turbo coupe high idle Reply #20 – August 09, 2008, 02:33:00 PM Codes are essential. Throwing parts at a car is just wasting money.To me, FWIW, it sounds like the TPS voltage needs to be re-set. Also, the base Idle has to be re-set. The IAC actuator may not be working right, clean valve or not. The ECT or IAT could be giving bad info to the computer. Your fuel pressure regulator could have ruptured.. See how expensive just throwing parts at a car is? Check the codes, it will at least set you in the right direction.From the code you have, the ECT could be the culprite. Start off my VERIFYING that the base idle/tps is set up correctly. If it is, the next step would be the ECT. The absolute bottom on the list would be the BAP. They don't go bad very often, and you would need a meter that can read frequency in order to test its output. I wouldnt worry about the 14 for right now, get the other stuff figured out and then go from there. Quote Selected
1987 turbo coupe high idle Reply #21 – August 09, 2008, 04:04:03 PM Was the car up operating temp when you got the codes?Double-check your TPS voltage as mentioned and perhaps look deeper into the ECT. I've rarely known those to fail though. Quote Selected
1987 turbo coupe high idle Reply #22 – August 09, 2008, 04:08:27 PM The car must have been at operating temp. It was driven for over an hour for a distance of approx. 50 miles.My temperature gauge rarely moves. After that trip it was barely over the blue line on the bottom of the temp gauge. Quote Selected
1987 turbo coupe high idle Reply #23 – August 09, 2008, 04:26:41 PM go pick up a code reader from AutoZone for around $100 bucks then get the Ford OBD I addaptior from Auto Zone to. Or buy the Ford OBD I addiptor and let Auto Zone connect to the code reader. Quote Selected
1987 turbo coupe high idle Reply #24 – August 09, 2008, 09:41:55 PM I already have the codes. See page 2. Quote Selected

It may need to be replaced. Quote Selected
1987 turbo coupe high idle Reply #26 – August 09, 2008, 10:25:40 PM The T-stat is only about 3 months old. How do I check my TPS?Also, right now its about 60 degrees outside and I tried to start the car to move it. IT idles at about 1000 rpm for about 15 secs kinda rough and dies. I've tried three times. If I step on the gas, it dies immediatly. Maybe htis helps. lol Quote Selected
1987 turbo coupe high idle Reply #27 – August 09, 2008, 10:48:09 PM Go back to the link on the NATO page I listed earlier. There is a procedure for setting your TPS/idle adjustment. Quote Selected

1987 turbo coupe high idle Reply #29 – August 10, 2008, 03:12:25 PM I adjusted the tps according to the NATO website. The problem is still here. I haven't checked codes again, but it still revs up to around 2000rpm after being driven a little and it warm. Only sometimes this happens thought. Quote Selected
