yay! Another problem!
 

ok problem number 2, i think my gearbox maybe fubar, its an auto, when its cold, and sometimes when its warmed up, 2-3 and 3-overdrive it dosnt want 2 change, revs go up speed only slowly increases, and it feels like its gona hit 8k rpm before it wants 2 change, also when its cold if u put it into drive it stalls like if u bring up a clutch, the weird thing is when the problem occurs the voltage rockets up 2 around 15.7-9 v.

to start with, check your transmission fluid, i thought mine was fecked after it had been up on axle stands for months, i started it up, put it in reverse and drive, but it wun't move, i toped the fluid up and worked the gear change back and fourth for about a hour, until it started to creep forwards, it did eventually right itself.:)

tried checking the level, but the dipstick would not budge! Me and niki pulling did nothing, leaving 2 soak so wd40 round it

check the vacuum pipe from the inlet fanimold. If still no joy email Silviagod

cheers will do, the fluid level was nothing 2 write home about, very small top up, il do another vacum check,

would say a low oil level/knacked diff be 2 blame?

the diff will have nothing to do with the Auto box

right in between the s15, bin tinkering with the s12, and ive noticed when this problem occurs, the fuel pump runs like the clappers and never switches off! Is there a fuel regulator on these cars? And ive checked the wires 2 the pump, would overfueling cause these probs?

Fuel reg is attached to the fuel rail. The auto box would work regardless

right the problem is now, voltage goes right up, idiling in neutral is fine, in drive etc it cuts out, idles too low, and if u try and drive it, its very sluggish, and wont change up, and fuel consumption is bad, then if i run it for 10mins, switch it off, then its fine. Then few hours later it wil do it again!
