Matt Harwood Posted August 19, 2006 Share Posted August 19, 2006 Booking at the moment for roughly a week or so in advance. Although if you're leaving it with me, it's not so much of an issue, you can drop it off anytime. Link to comment Share on other sites More sharing options...
Steve Posted August 19, 2006 Author Share Posted August 19, 2006 Have got all this week off so, if the ECU dont work will try and get it down to you. Is it best to ring first? Whats the cost per hour? £1.50 Link to comment Share on other sites More sharing options...

Steve Posted August 20, 2006 Author Share Posted August 20, 2006 Have taken the advice from Matt and took all the intake side apart, to get to the seals form the head to inlet runners and inlet runners to the intake plenum. The seal that goes between the runners and the head does look quite poor, all the plastic covering on the seal is flaking away. So could be causing an air leak. Will order some new gaskets tomorrow from Toyota. Is there anything that i can do the runners and plenum whilst they are off the car? The runners do have some crap inside so could do with a clean. What can they be cleaned with? Thanks Link to comment Share on other sites More sharing options...
Steve Posted September 21, 2006 Author Share Posted September 21, 2006 **Update** Right have changed all the intake seals around the inlet runners, plenum, throttle body, IACV and the injector seals. Fired it up today and its still the same I tried another stock ECU and its still the same The only thing i can now think of is where the car has been sitting it has blocked up the injectors, i do use Tescos fuel so dont know whether it dont like sitting for a while. So am gonna remove the injectors and get them tested and cleaned and see what happens. Link to comment Share on other sites More sharing options...
Sheefa Posted September 21, 2006 Share Posted September 21, 2006 Jesus Steve this has been going on a while pal. Good and bad news though - the 'Good' (lol) news is I'm having EXACTLY the same problem, the bad news, I'm having this problem! and I haven't tested anything or got it sorted yet as don't have the techy techy knowledge! Mine can idle between 13-15 at anytime. Today I put my foot down and it raised to 15.5, took foot off accelerator and it dropped to 13 for a split second then back up to mid 14's. It never runs rich or below 13 for more than a few seconds. Bascially, I too am running lean with average between 14-15 all the time - it's damn scary. Mine's a J-spec TT with Hybrids and standard injectors. No fuel management ECU or the like. I have an AEM UEGO Wideband AFR gauge which was plumbed in by Phoenix Performance in May 2006. I have no idea what's wrong. The good news is thast I'm taking my car to Chris Wilson this saturday to get it tested so he'll hopefully 'cure' the problem and I'll let you know the results. Good luck buddy. Greg Link to comment Share on other sites More sharing options...
Steve Posted September 21, 2006 Author Share Posted September 21, 2006 Tell me about it mate I am determined not to be beaten though Let me know how you get on mate, could be the same thing causing it as it does sound exactly the same.

Sheefa Posted September 21, 2006 Share Posted September 21, 2006 Yeah pal will do. It's doing my frikking head i too and only got the car weeks ago! Check video all of my AFR problem readings. It's a phone 3gp file. Sorry Thanks http://download.yousendit.com/22C3BA42257EA8D9 Link to comment Share on other sites More sharing options...
Steve Posted October 1, 2006 Author Share Posted October 1, 2006 Right have had the injectors cleaned, before cleaning they were ok and the spray pattern was fair, but now Good. Refitted them and tested the car, it has stayed the same. Also tried changing the Water Temp Sensor on Gregs advice (thanks for the loan sensor) and it seemed to start working ok. But after a few seconds it went back to running lean. Came back home and checked all the connections to everything, went out again and found it would intermittently go lean, not all the time like it had been. Tried it again this morning and its just doing it randomly, one minute the AFR's are perfect, then the next minute it goes lean. So something like a sensor could be doing this. Any ideas??

Steve Posted October 1, 2006 Author Share Posted October 1, 2006 Just put the Water temp sensor in the freezer for a while and put the meter on it and it still has the same reading that it had while at room temperature. According to the manual it should be between 4-7k at 0 degrees and at 2-3k at 20 degrees, it seems to be staying at 2-2.5k. Just goimg on what Greg said that if this sensor was fooked it could make it run lean or rich depending which way the sensor was sticking at.

Sheefa Posted October 1, 2006 Share Posted October 1, 2006 Steve and Rich. I have the EXACT same symptoms too. My AFRs can be great one minute and then suddenly in an instant second switch from 13 to 16 and stay there for a while. If I turn the engine off and restart it'll stay at 14 then slowly rise to 15ish. I also have a problem starting when the car is warm. Link to comment Share on other sites More sharing options...

Sheefa Posted October 1, 2006 Share Posted October 1, 2006 Thanks Rich. Car is with Chris Wilson at the moment so hopefully he'll do the testing and sort it - but I'll pass this message on! Where abouts can you get a new coolant temp sensor from mate? Thanks again BTW - Has anyone managed to view the vid of the random AFR readings? It's in phone 3gp format but can be converted.

Steve Posted October 1, 2006 Author Share Posted October 1, 2006 Mine always starts first time everytime, when warm or cold. Gonna try and get a new sensor from Toyota sorted out and give that a try. Link to comment Share on other sites More sharing options...

Homer Posted October 5, 2006 Share Posted October 5, 2006 Your vid of the AFR gauge looks perfectly normal mate, it'll be swinging all over the shot while off boost/low boost. AFAIK the reasing is only really relevant on a stock TT when the 2nd tubbie is online. If poss get a vid of you cruisng at 3500rpm, then floor the throttle until near max RPM. No use doing in lower gear, must be high gear (3rd auto, 4th or 5th manual). If its anything like mine it will have a nasty lean spot between 4000rpm and 4500rpm then at 11.8 until redline (1.25bar) Edit - btw above is aimed at Sheefa Link to comment Share on other sites More sharing options...

Steve Posted October 6, 2006 Author Share Posted October 6, 2006 Is there anything electronic on the throttle body that would cause this? I know there is the Throttle position sensor and the TRAC butterfly control, but what is the other plug and wires for? Link to comment Share on other sites More sharing options...
Alex Posted October 6, 2006 Share Posted October 6, 2006 I've not read all this, but does it run properly with the old injectors and no piggyback ecu? Does it run all right with the old injectors and the EM running a ZERO'd map? Link to comment Share on other sites More sharing options...
