michadoo Posted May 7, 2005 Share Posted May 7, 2005 the speedo on our s2 R33 is continuously dropping out and wont come back unless you give it a small bang on the dash. we took it to our mechanic and he hooked up some computers or something to it and said he couldnt really find any problems with why it would be cutting out, maybe just get a new one. We are also having that stalling problem where it will drop rpm drammatically until it stalls. at first we thought the stalling was caused by the speedo dropping out and there not being any speed reading, but think it could be something more sinister i have read the thread about the stalling problems, with the fuel pressure, but wanna know if anyone else has had any problems similar to this and if it could mainly be a wiring and electronic fault or something else. has anyone else had this problem? cheers M&B Link to comment https://www.sau.com.au/forums/topic/72760-spedo-drop-out-and-engine-stalling/ Share on other sites More sharing options...
SRG33 Posted May 7, 2005 Share Posted May 7, 2005 Hey B&M, I have only had my 33 since feb this year and wouldnt consider myself an expert but thought i might as well chip in my 2c worth.. At first i was getting the same stalling problem where the revs would just drop till it stalled.. I dont know if this will work in your case but the problem i found was that i was kaning it and dumping it straight into neutral.. It might just be your driving style, as was the case with me.. To do this in a N/A car is ok but it seems the 33s or just turbos in general dont like it.. So always have it in reasonably low rpm when changing gear to neutral... Another words always put it into gear after you have kaned it and then into neutral... Hope this makes sense, but its helped me.. havent stalled it since...

Sparki_D Posted May 7, 2005 Share Posted May 7, 2005 Check for a boost leak, check your vaccum hoses, tell more about the behaviour of the motor, is it only at idle? or under throttle too? Standard Computer? Remeber that the stock ECU doesnt like a BOV that vents atmo, tends to cause the car to stall as well.

Skyrine-Dave Posted May 7, 2005 Share Posted May 7, 2005 ok this is a very far out idea... but if your speedo drops out and your car stalls is it possible that your gearbox loom is dodgy/broken, if your speedo drops out- that is on the gearbox loom, if your car stalls the neutral switch is on the gearbox too..

michadoo Posted May 7, 2005 Author Share Posted May 7, 2005 yea we have a turbosmart bov. we noticed the stalling only really started after we got an alarm and immoboliser installed aswell - could it be a coinsidence? doesnt stall by dropping it into neutral dont really drive like that, just stalls if you are coming up for a stop or something the rpms drop heaps quick. if you keep an eye on it you can usually tell if it is going to drop too low in that case just tap the ecellorator to bring the rpms up abit. just getting really frustrating and anoying, can be really embarrasing too! it doesnt always stall when the spedo cuts out, the spedo can be really intermitant, we thought that the stalling may have something to do with it but cant be too sure.gear box is in good condition. maybe something with the electrics??

krzysiu Posted May 7, 2005 Share Posted May 7, 2005 Take off the BOV and replace it with the standard plumb back and i think that would solve your problem.

michadoo Posted May 8, 2005 Author Share Posted May 8, 2005 tried the stock BOV still the same problem, thinking maybe when we got the alarm installed they may have done somehting to the electrics??

R33S2 Posted May 8, 2005 Share Posted May 8, 2005 Sounds like electrical to me from reading your imput. If it was me I'd take it back to ppl who installed imob and tell them whats been happening and get them to check all thier connections.

caminperth Posted June 16, 2005 Share Posted June 16, 2005 I'd say you have two separate problems. Stalling like this on std BOV sounds like something is leaking somewhere. Check all piping, hoses ect. I've got the same speedo problem, a bang on the dash seems to sort it and once it's been working for a while it doesn't drop out anymore. I've had the cluster out for closer inspection and couldn't find anything obvious, but if banging the dash fixes it, there must be a loose wire there somewhere. If anyone finds what causes the speedo problem, please post!

nismo180 Posted June 16, 2005 Share Posted June 16, 2005 I've recently bought an R32 GTST and the car would stall randomly. I changed the fuel filter, spark plug and checked all hoses but that didn't fix the prob. What I then did was perform the ECU Diagnostic and and showed code 12 which is the Air Flow Meter. So I borrowed a mates AFM and the car now runs really good. It doesn't stall anymore. Its a very simple process: just take off the ECU from its mounting Turn the key to ignition, but dont start the car turn a knob on the back of the ECU anticlockwise, then clockwise again Depending on what model you have, LED lights will flash according the the fault. Just search on the net for instructions to do the ECU Diagnostic, and that should tell you if there is a fault .

MsG_ChRiS Posted June 17, 2005 Share Posted June 17, 2005 my r33's tacho has just stuffed up it drops out sometyms and i have to give it a lil bang on the dash... i noticed this to after i got the immobiliser and alarm installed too!!! so mayb they stuffed some of the wires under my dash when they took whatever out or cut whatever wires? should i just get a new dash ??? <--- how does that work do you order the new dash from nissan or something ??? wouldnt it have zero kays on it but also??? or should i take it back to the place and get them to double check what they're work???
