Hello all turbo-Ford owners!
Greetings from freezing Finland (North Europe)! I´ve been an owner of 88 TC for one and half years now and I can tell you that TC is quite a rare car around here. My TC is very original and mileage is only 87 000. I have liked my car very much, it's great driver and surprisigly fast. Originally it was equipped with automatic but A4LD didn't like my driving style and blew on last spring. I was lucky and was able to locate T-5 and other parts from here (from 90 4-cyl Mustang) and so now my TC is equipped with 5-speed.
But there is a very irritating problem, rough and irratic idle. I have set the basic ignition timing to 10 degrees and base idle to around 800 rpm without IAB. When I reconnect the IAB, idle sets up to around 1000 rpm, so feels that everything is ok. But very often idle rpm rises to around 2000 rpm and stay there, sometimes when driving sometimes when idling. There is no logic at all. Usually this problem occurs when engine has warmed up but sometimes it does this also when engine is cold.
Spark plugs are almost new Boschs, spark plug wires are new Ford Racing 9mm ones, rotor and cap are ok, IAB and EGR are cleaned and TPS adjusted. EEC Self diagnosis doesn't give any trouble codes exept when car has idled few minutes with high rpms. Then CE light appears and code 42 (rich mixture) appears to continuous memory. CE light disappears when throttle is depressed and car accelerated.
When engine is idling high, disconnecting the IAB gets rpms to drop to normal 800. Could there be a problem with that IAB even though it's cleaned and works usually fine. Or could this problem be caused by some broken sensor ,ACT maybe (I have changed the temperature sensor already).
There is also a problem to get the car started when it's very cold (around 0 F), feels that cold start enrichment system doesn't work very well. Engine doesn't get rich enogh mixture to start (just like trying to get old carburator engine started without choke). When engine has started it runs quite smooth and ok, rpms around 1500 for a while. Could these problems be linked to each others somehow?
Thank you all for answers! I start to feel desperate because this problem has been around for months and feels that nothing helps!!
