Hey guys I need help , my vl keeps cutting out . It mainly happens after sitting in the sun or after heating up abit what happens is it won't rev past 2 and a half then it just cuts out until revs drop to 1000 then it fires back up and this just keeps repeating . THE THINGS IV DONE New crank angle sensor and plug New airflow meter Coil All fuel pumps and checked fuel pressure Also had another comp in it Checked temp sender My speedo and afew other dash gauges dont work could it be like a speedo sensors or something ? I'm out of ideas so if any1 can help please do thanks. ---------- Post added 09-12-11 at 15:36 ---------- Come guys surely some1 has afew ideas this thing is doing my head in ---------- Post added 09-12-11 at 15:43 ---------- Come on guys surly some1 has afew ideas to put out there , this thing is doing my head in

Bump

only thing I can suggest is injectors? or the filters inside them being blocked.. or just some grounding wiring somewhere or possibly your TPS. is your ECU throwing a code? could be timing or maybe its leaning out? would have to be there and hear it. does it struggle or do anything out of the ordinary before it hits 2500

Sounds like classic CAS open circuit, since you mention it only happens when it's warm. Possibly a break further down the loom? The Gregorys/etc aftermarket manuals have details on how to check for open circuits with a multimeter between the plugs at sensors at where they enter the ECU.

just went thru the same thing with my daily, pull the dash cluster cover off and check all the plugs are connected to the cluster properly

mine did this. it was the cas plug. wires were heating up and breaking contact when it got too hot. ongoing battle. in the end just replaced the plug entirely.

Thanks guys since asking for help iv again put a new CAS plug on checked every possible fuel related thing , all wires connected in the dash cluster , new oxy sensor. It's like it's actually going into a limp home mode ?

tried replacing the ecu?

yeah he tried a different comp already, is it when it comes on boost? is there a difference when its on or off boost at those revs?

Try battery and connectors! Also where your earth goes on to you block! Could be loose or dirty!

maybe get the car to a place where they can run it on a dyno and start checking things but i would think its the CAS or try another dizzy from another car

Na dosnt get a chance to come onto boost, I might have to trailer it somewhere it's been at the auto elec for 3 days already . The strange thing is its only under load and moving its strange

dtall it up on the brake and try and get it on boost, see if theres a difference? if it comes on boost and revs abit better then that means its leaning out off boost maybe

disconnect your speedo from your gearbox and see if it lets you rev past 2000rpm, i just went thru this i gave up and am now goin aftermarket ECU

I would check your fuse box and make sure all relays and fuses are ok. I had an issue where the relay for the fuel pump was starting to melt and it would cut in and out. Pull them all out and check them one by one. Sorry i meant fuse/relay block was melting, not the actual relay.

So iv Worked out that it's cutting out of fuel it's getting to 2000rpm then something is cutting it out of fuel any ideas ? Sorry to be a pain guys but all ur help is appreciated

So this problem continues to happen any other advice guys maybe something iv missed? Everything that has been mentioned has been tried

So after a long head ach it's finally solved thanks for help guys

What was the problem?

Dry solder joint in the auto trans comp
