pva glue.

It still could be instrumental. Get it checked out and stop being a tight ass LOL. No honestly the readings are taken off the coil. Could be faulty wiring or connections or the tacho itself. get it check out by a mechanic or auto electrician.

good luck friend. :P

:( I had a similar problem and got auto repair after repair to hunt down the wiring, checked all the engine managment and sensor and was fine. Adventually I got of my ASS and replaced the Tacho all fixed, mind you the Tacho wasn't cheap!

Where is Tacometer sensor is located?

I think mine is bit out of scale...:D

cheers

There isn't a 'Tacometer[sic] sensor' as such, the ECU gets the angle of rotation of the camshaft from the CAS (Cam Angle Sensor), from this it can calculate the speed of rotation of the crankshaft, and using this generates a negative pulse for every rotation of the crank.

This pulse is the signal on pin 7 of the ecu, and that is what the rev counter uses.

Sounds to me like a problem with the rev counter instrument itself or the wiring between the ecu and instrument cluster, as there is very little that could go wrong with the ECU.

      Price seems pretty good to me. Also seems a hell of a lot cheaper then buying another vehicle that only ever gets used for towing.  I'm a long way from you mate, I'm a couple of hours out of Brizzy.

      The sodium acetate, mixed with citric acid, doesn't actually buffer each other. Interestingly though, if you used Sodium Acetate, and acetic acid, THAT becomes a buffer solution. Additionally, a weak acid that can attack a metal, is still a weak acid that can attack a metal. If you don't neutralise it, and wash it off, it's going to be able to keep attacking. It works the same way when battery acid dries, get that stuff somewhere, and then it gets wet, and off it goes again breaking things down. There's a reason why people prefer a weak acid, and it's because they want TIME to be able to be on their side. IE, DIY guys are happy to leave some mild steel in vinegar for 24 hours to get mill scale off. However, if you want to do it chemically in industry, you grab the muriatic acid. If you want to do it quicker at home, go for the acetic acid if you don't want muriatic around. At the end of the day, look at the above thumbnail, as it proves what I said in the earlier post, you can clean that fuel tank up all you want with the solution, but the rust that has now been removed was once the metal of the fuel tank. So how thin in spots is your fuel tank getting? If the magazine on the left, is the actual same magazine as on the right, you'll notice it even introduces more holes... Well, rust removal in general actually does that. The fuel tank isn't very thick. So, I'll state again, look to replace the tank, replace the fuel hanger, and pump, work out how the rust and shit is making it past the fuel filter, and getting into the injectors. That is the real problem. If the fuel filter were doing its job, the injectors wouldn't be blocked.

      Despite having minimal clothing because of the hot weather right now, I did have rubber gloves and safety glasses on just in-case for most of the time. Yes, I was scrubbing with my gloves on before, but brushing with a brush removes the remaining rust. To neutralize, I was thinking distilled water and baking soda, or do you think that would be overkill?
