hello everyone... i know you are all probably sick about talking about the problems with vl's, but i need to find out what is wrong with mine. 3 weeks ago i bought my second car, replacing my old honda civic 87 which i only had for 1 month. happy with what i paid for, i went on my merry way with the new beast. that all changed last monday, when driving home from work the car felt like it was shaking a little bit, and it had absolutely no power. i still had power steering and all, nut my foot was on the floor and was getting slower. it sounded sick, like it was almost going to stall, and eventually died. i called racq and got towed back home. they did a quick check over and so did a 3rd year apprentice friend of mine and everything appears to be ok, sparks, battery good, etc, etc, etc, all working condition. it blows no smoke, it turns over and dies straight away now, so i was just tryin to find out the problem, cuz i dont want 2 pay a moblile machenic anythin, cuz he might say " u need a auto-electrician" or sumthin, waste of money and im all ready poor.... i've heard of CAS(crank angle sensor??????) n dizzy's but dont know wat they are, if u think thats the problem could you tell me where they are? thanks -johnno-

could be fuel pump or air flow metre

nah it wont be the AFM if it was it would be blowing smoke out which -Johnno- said it wasnt

is the throttle position sensor at all meen moved or is moving.....little black box on the side of the throttle buttifly area.... check that out first.... even my 2.5 did this to me last week the screws came loose and no start pinging tries to run than dies....long story short it got a timing belt waterpump as i had the belt of etc etc etc.....

the air flow metre is the balck box at the right front side of your engine bay my bet it's that. unscrew and have look at the wires to see if they are snapped behind the metal filter

u d**k thats the air box. the AFM is the bit where the plug puggs into, just before the air box

tps is only for the gearbox doesnt run the engine.and afm causes all different problems aswell. but i reckon its the fuel pump **** itself test that first take the fuel line off and turn on the ignition and fuel should piss out if it only dribbles its the pump.

check ur CAS, its in the dizzy (distributor) which is the circle black thing that all ur sprark plug leads go into

When my afm stuffed up I bought a second hand one that included the box. When I said box I mean air flow metre. Don't jump to conclusions. Didn't wanna get in to too much detail.

check the AFM, fuel pump and crank angle sensor.

tps only runs gearbox.

Quote: tps only runs gearbox. once again it does both, the motor sees a on or off sig, if at idle it sees an off sig ( i think) it will play up and thus resulting in needing adjustment. what u will notice is like a funny miss apon giving it revs than it will come good tps is out tps does auto box and motor. this is why there are 2 plugs and when a manual is installed there is only one plug off the tps..... sorry dude i think tps is not at foult in this instance but it was worth a check anyways want it?

I wonder if the previous owner had changed it b4hand? holden CAS aren't that good. Check it out dude.

any luck fixing the problem?

Check it out dude. my car was doing the same thing and we cleaned everything inside the dizzy.... but u said the holden CAS's arn't good.... if they need to be replaced... what do u recomend replacing them with?? Cause i cant see the point replacing it with another VL CAS.... Some original photos have not been recovered yet.

From what I've gathered the R31 skyline has better built CAS item than the one in the VLs. Just go to a wrecker or one of those PICK A PART place. Remember to bring a 8mm socket with extension and a phillip screw driver.

some times its not the crank angle sensor i rember manny times after i washed my motor (cover the dizzey) it used to swamp with water and it just needed a good blow out with compressed air. water enters via the plug which also bugges the plug. pull the cap off remove the plate and blow off the optics and plate, give this a tri.

The motor reads from this to calculate A/F ratios along with all the other input sensors like CAS, AFM and o2 Sensor....... My Haltech came with its own TPS mate so how in the f uck does that even come close to relating to the gearbox? If the TPS is moving with the throttle butterfly the car will run like ****, end of story! It must be fixed in place and calibrated. Some original photos have not been recovered yet.
