Tha Dragon Posted October 8, 2013 Share Posted October 8, 2013 Hi guys, Don't know if this happened to one of you, but i was driving to work today, all of a sudden "Check Engine Light" starts flashing and "RPM" gauge starts going up and down like crazy. Before today if i put down a street race and after that come to a stop or at the lights it will "Idle" very low or turn off on it's own and takes time to turn back on. can one of you guys let me know what the problem could be?

Chris Green Posted October 8, 2013 Share Posted October 8, 2013 Check the throttle position sensor. Had this problem on Sunday night. Quote Link to post Share on other sites
Tha Dragon Posted October 8, 2013 Author Share Posted October 8, 2013 Is there a Chance you can send me a pic of where it is located Quote Link to post Share on other sites
Chris Green Posted October 8, 2013 Share Posted October 8, 2013 It's on the throttle body, if your looking down on it, it's at the back, a black square box. Quote Link to post Share on other sites
rasslenny Posted October 8, 2013 Share Posted October 8, 2013 (edited) on top the intake manifold there is a little circle piece of rubber its like a little cap beneath that is a screw that controls your idle.... if the screw has become loose and unscrewed it self enough the idle will be way tooo low to keep the car running it has happened to me already after a very and i mean very spirited bit of driving its an easy fix ... flat head screw driver is all you need screw the bolt in a little and turn the car on.... then you adjust the idle the same way screwing it till its where it needs to be a little under 1000rpm on idle is where i have mine Edited October 8, 2013 by rasslenny Quote Link to post Share on other sites
rasslenny Posted October 8, 2013 Share Posted October 8, 2013 (edited) if it isnt that then id think u may need a new tps its the black box to the back of the intake manifold looking down at it next to the throttle boddy repost lol... as chris said above Edited October 8, 2013 by rasslenny Quote Link to post Share on other sites

Tha Dragon Posted October 13, 2013 Author Share Posted October 13, 2013 Hi guys gonna check it out today it has gotten worse, it keeps flashing the "check engine light" and "rpm" gauge keeps acting crazy and about the "TPS" do you have a diy guide or some on how to remove and install the "TPS"thanks in advance guys Quote Link to post Share on other sites
Chris Green Posted October 13, 2013 Share Posted October 13, 2013 It really isn't hard to check mate, little black box on the back of the TB, just check the wiring for a start. There are 3 wires in the plug that connects to the TPS. Quote Link to post Share on other sites
Tha Dragon Posted October 13, 2013 Author Share Posted October 13, 2013 Ok, but can I just remove it and put another 1 in it's place? Quote Link to post Share on other sites
Chris Green Posted October 13, 2013 Share Posted October 13, 2013 No, as far as I am aware the FTE ones are 'slotted' meaning they need to be adjusted. I'm not sure if there is a guide on here. To reset the TPS you need rotate it while on the butterfly pin 360 degrees anti-clockwise. - This is from memory, I remember reading about it somewhere. But two small bolts hold it in place. If you have a strut brace, it would be easier to work with if you removed it. Quote Link to post Share on other sites
Tha Dragon Posted October 13, 2013 Author Share Posted October 13, 2013 Ok, I'm gonna try it out I have an engine in my back yard gonna take it off and put it on mineI'll keeep u posted thanks Quote Link to post Share on other sites

Chris Green Posted October 13, 2013 Share Posted October 13, 2013 Yeah, that looks spot on mate. As I said check the wiring first. Quote Link to post Share on other sites
Chris Green Posted October 13, 2013 Share Posted October 13, 2013 (edited) Sound have mentioned this first. Run the self diagnostics. Bridge ports E1 & TE1 and that will give you fault codes on the dash. Here's a guide http://www.ukstarletowners.com/topic/9295-how-2-perform-a-diagnostics-test/ Edited October 13, 2013 by chrisgreen1993 Quote Link to post Share on other sites
Tha Dragon Posted October 13, 2013 Author Share Posted October 13, 2013 Ok, I'll let u know Quote Link to post Share on other sites
Tha Dragon Posted October 13, 2013 Author Share Posted October 13, 2013 I did the diagnostics it flashes 34, turbo pressure signalwhat do I need to do now, I replaced the "TPS" already so what now? Quote Link to post Share on other sites
Chris Green Posted October 13, 2013 Share Posted October 13, 2013 Don't know where to go from there mate. I don't have a clue about turbos. May be worth changing the title name. Quote Link to post Share on other sites
Tha Dragon Posted October 13, 2013 Author Share Posted October 13, 2013 Turned it on, no check engine light no nothing I'm gonna let it run idle 4 a bit wash the car and take it for a spin I'll let you know Quote Link to post Share on other sites
corofin12345 Posted October 13, 2013 Share Posted October 13, 2013 if your rev needle is jumping its not the TPS.. reset the ECU (disconnect the battery for 5 minutes, then re connect) and go for a drive and if the EML comes on, do the diagnostic test again... its distributor related, you may of even skipped a tooth on the timing.. may be worth timing the engine when your at it Quote Link to post Share on other sites
Tha Dragon Posted October 13, 2013 Author Share Posted October 13, 2013 Before the story I just wrotethe EML never came on but I was driving 1 day and all hell broke lose, EML stared flashing, rpm needle started jumping up and down, now I need to take it for a spin tosee if it's ok Quote Link to post Share on other sites
