mikevr6 0 Posted April 8, 2014 Report Share Posted April 8, 2014 Brought the VR6 out of hibernation at the weekend. Battery was completely flat after sitting for 6 weeks so a jump start was needed. Took her for a 40 mile run to charge the battery and shake the cobwebs out.Had her out again last night, started on the button. 20 mile drive, no probs.This morning on the way to work she drops below 500rpm and cuts out every time I take my foot off the gas. If I try to start her with no gas she just turns over. A little pedal and she starts but cuts out again as soon as I ease off. Unfortunately I can't find my OBD cable at the moment to run a scan. What should I check? Link to post Share on other sites
Ickyketseddie 89 Posted April 8, 2014 Report Share Posted April 8, 2014 Start by checking for an air leak around the inlet/throttle body. Might be worth doing tb alignment too when you find your cable. Are you obd1/2. If you have an itv check that too. Sent from my iPad using Tapatalk Link to post Share on other sites
mikevr6 0 Posted April 8, 2014 Author Report Share Posted April 8, 2014 All Corrados are OBD1 iirc. Throttle body alignment seems to be the general consensus from reading other threads. I'll check under the bonnet for leaks too.The engine was recently rebuilt at Stealth, so the throttle body and ISV should be ok. Link to post Share on other sites
mikevr6 0 Posted April 9, 2014 Author Report Share Posted April 9, 2014 I think I'm going to have to take the ISV off and test it. If it's not clogged with dirt, it could be the solenoid is getting lazy. Link to post Share on other sites
Jimjon 28 Posted April 23, 2014 Report Share Posted April 23, 2014 How do you do a throttle body alignment on a corrado vr6? Link to post Share on other sites

mikevr6 0 Posted April 23, 2014 Author Report Share Posted April 23, 2014 Ok. Throttle Body Alignment on a Corrado is not possible. They don't have a motor driven TB. You can do the ECU rest procedure and "Basic Settings" though.http://wiki.the-corrado.net/vr6_ecu_reset_procedure.html I cleaned the ISV and tested it. All ok. Made no difference.With my car being SuperCharged, the MAF is located down behind the bumper. I took the connector off and cleaned the connections and that improved things for a while. I'm going to try and get the sensor out of the MAF tonight and gently clean it. I also have a spare MAF I can try.What sort of torx are on the MAF sensor? I can't really get a look at them where they are. But they feel odd. Link to post Share on other sites
mikevr6 0 Posted April 24, 2014 Author Report Share Posted April 24, 2014 (edited) Weird little torx they were with a little nipple. Luckily my latest Aldi purchase of a 120 piece screwdriver set contained the right bit.Swapped the MAF over last night and the car drove beautifully. Had a nice 30 minute blast around the countryside. Parked her up for the night with a smile on my face. Started her this morning looking forward to a trouble-free drive to work. Nope! The bag of spanners is back. I'm getting miffed now. Edited April 24, 2014 by mikevr6 Link to post Share on other sites
mikevr6 0 Posted April 24, 2014 Author Report Share Posted April 24, 2014 VAGCOM00537 - Lambda (Oxygen Sensor) Regulation11-10 - Control Limit Not Reached - Intermittent00553 - Mass Air Flow Sensor (G70)29-10 - Short to Ground - Intermittent00513 - The Usual Engine Speed Sensor Fault when running VAGCOM with the engine off.All of these are historic faults. IE: before I replaced the MAF sensor. So I cleared them and I'll take it a drive tonight and rerun VAGCOM. It could be a Lambda fault but I tend to think this is showing an error because the MAF has been faulty. Could also be a wiring problem. Stealth will have extended the MAF wiring to relocate it behind the bumper. I'll try and trace the join. Must "borrow" a multimeter from work I've also just ordered a new Bosch MAF. Which should arrive on Monday. I'll grab the part no of the sensor itself when it arrives. Link to post Share on other sites
Bealieboy 1,625 Posted April 24, 2014 Report Share Posted April 24, 2014 I've heard a faulty maf can throw all kinds of other codes when they go tits up. What kind of air filter are you running as the open cone style are known to balls maf sensors right up due to the oil used in them. Doesn't one of the temp sensors give running problems too?

mikevr6 0 Posted April 24, 2014 Author Report Share Posted April 24, 2014 It's a big K&N cone that came with the charger kit. The old MAF wasn't dirty when I checked it either. I ran a cotton bud over it and it hardly had a speck on it. But I'm sure being way down low at the front of the car doesn't help the connector. It must be getting all the crap sprayed at it.
