Thank you Mark:) Very clear. I will try to get to the scoping over the next 2 days and report back. Andy.

Hi Mad1stGen. What worried me was the fact that with the metal rod missing and the black arm and actuator held in place where it should be, it didn't feel right. I made sure the plastic backplate was trimmed down like you did so it was able to go to its full travel. What worried me was the...

Right, here is a wiring diagram for the EATC and blend door actuator. Its pretty evident that the black arm swings way too far one way and the other. So we need to convince the EATC module to stop the arm earlier. In the wiring diagram above there is a potential divider circuit at pins 4, 3...

Just done my blend door following the really good instructions here...... Usual broken part But, notice this........ I had to drop the steering wheel because the dash wouldn't pull out even after all the fasteners were removed. After checking and double checking I finally figured out...

+3 !!!!!!!!!!! Andy.

Thank you. I will indeed check that out. Andy.

Had a PO340 code today! Camshaft position sensor circuit failure. Cleared the code and unplugged the sensor and plugged it back in. Not reoccured and drives well. Decided to scope it to have a look at the signal. Blue line is the signal line and the just visible red line is the signal ground...

yeah, sorry - I meant the 1v line! You could be right. I'll scope the sensor ground and supply later just to be sure. Andy.

Thats roughly what I paid over here. Very good though. Whether its $1000+ worth, time will tell;) Setting up the pico for a TPS voltage check. So, here's the voltage at the signal wire to the PCM from the TPS. I made 2 full throttle openings from under the hood by hand (which is why the...

No. Here we have a waveform at the battery with engine at idle Heres the voltage waveform at the IAC (idle air control valve) with engine at idle and no electrical load Here it is with AC and lights on Since this is a pull down circuit, the low bit on the steeped waveform is the on time...

Sorry. 1997 2nd gen COP Andy.

Hi Guys. I would like to start a thread of good mark 8 scope waveforms. They are a superb, unbeatable diagnostic tool as long as you can find somebody to do it!! If anyone and everyone could add to these it would be good. Anyway, heres a waveform of one of my primary ignition coils The next...

Got fed up of pass headlight fogging up and producing condensation, and couldn't find the leak, so I smoke tested it. Heres a link to youtube of the smoke pouring out of the join where the lens is glued. Amazed the hell out of me! http://www.youtube.com/watch?v=3YgmMqWsYuc&feature=youtu.be...

Hi Steve, Can happen at anytime, but only after a key cycle. Park on a flat surface. Andy.

No!! Andy.

hi all. i've been hunting down an erratic fuel gauge reading (one day reading 1/4, next 3/4 etc) and have already changed the fuel tank sending unit as part of a fuel tank restoration, but the problem continues. I have used the NGS tester to command the gauge and this is what I got 10% command...

Nah - not for me. Proper part or improved part only! Car successfully fired up today and the fuel gauge looks like its working okay! Time will tell though. Here's 3 photos of the inner workings of the sender unit showing the wiper on the track. Both look well worn. Andy.

Hi beerdog. Yes, I did! But obviously not! Got to find out whats going on. Thank you anyway. Andy.

Hi mad1stgen. Ooops! Posted this on the wrong forum:confused: BUT still no word from them. I've posted up to ask them whats going on. Till then I suppose I've got to wait till I find out if one is actually going to be sent! May end up with 2 then!! Can I keep you posted? I may need your...

Hi again guys. I'm assuming I have to look elsewhere for this part then? No word. Would someone just tell me the state of play? I don't mind if its not possible to send the part, but I need to find it somewhere else if thats the case. Cars not moved since december so need a decision on...
