Did you change the fuel filter?

Couple of ideas i've plucked from a few searches... most of them probably irrelevant...

-My fuel injectors were the cause of my erratic idle. I determined this by OHM'ing out using a multimeter (avg 14.4 OHM) if its below 12OHMs its time to replace. (I don;t know what this means...)
- Checked for Vacuum leaks and replaced any old hoses that could be a possible culprit.
-Replace your spark plugs

well duuuh ( make sure they are properly gapped) make sure your plugs are tight or you will lose compression.
- TPS and IAC may need adjustment and/or replacement
- IAC may be dirty...
-Oxygen sensor (gets wornout frequently 30$ replacement)

Almost everywhere I look it keeps coming back to the same things, MAF Burnoff, dirty MAF dirty IAC (whats that?), TPS, faulty relays / bad wiring or contacts.

Gator · « **Reply #35 on:** April 24, 2008, 08:16:36 pm »

same here mate thats what i come up with iac tps ect

will do IAC tomorrow
no idea what the hell maf burnoff is
i aint done the plugs but cant see it being that

its the instant death when i put it in gear that makes no sense

found one guy with same symptoms and it was the head gasket........gulp

FUBAR · « **Reply #36 on:** April 24, 2008, 08:19:31 pm »

uh oh... still if it is the head gasket its a cheap fix if you do it yourself... its just a shame about the man hrs involved... drive it to the show, we'll do it on Saturday

well i did the headgaskets on the granny drilled out the broken stud, port and polished them an the intake all in a day and a half

55starchief · « **Reply #38 on:** April 24, 2008, 08:26:40 pm »

1st step would be a compression test though

Gator · « **Reply #39 on:** April 24, 2008, 08:27:29 pm »

heres a question when you sort terminals a and b on the diagnostic block to extract codes should this make the fuel pump operate

i assume its the fuel pump

something is making a humming sound under the car

dont sound right to me

FUBAR · « **Reply #40 on:** April 24, 2008, 08:31:09 pm »

the humming sound from the rear of the car is the fuel pump pressurising the lines, ~~and no as far as i'm aware it shouldn't do that.~~

Correction, you have to turn on the ignition (without starting) after shorting the terminals to read the codes, so this is normal behavior in preparation for starting the car.

Which by the way you should wait for it to stop humming before starting the car...

FUBAR · « **Reply #41 on:** April 24, 2008, 08:48:06 pm »

If its stalling when you put it in gear could it be a problem with the Torque converter? anyone else know if this can happen? could a wiring fault or short circuit cause it to lock up?

Edit: If you stick the arse end up in the air on stands & with the front wheels chocked (for some Martyn stylee H&S), with the handbrake off then start it up & engage drive or reverse will it still die...

Gator · « **Reply #42 on:** April 24, 2008, 09:03:49 pm »

good point will try that Ryan cheers mate

philoldsmobile · « **Reply #43 on:** April 24, 2008, 10:49:27 pm »

is the fault engine hot or cold? a weak spark can produce a stall in gear, will get worse as it gets hotter..

reading through the original post again, i think you may have a vacuum leak somewhere, with injected cars, if there is an air leak, it will idle faster, as it simply throws more fuel in to compensate. if its up stream of the MAF, its unmeterd air and the discrepancy between the air the MAF sees and the reading the o2 sensor sees (basically the unmeterd air) may fool the car into thinking the MAF is faulty...

its an old car, so perished hoses are very likely. Does the cruise control work? if not, I'd start looking at the vacuum hoses that go to the cruise control. its amazing how many running faults can be traced to non functioning cruise control units with vacuum leaks

Like my old car... however that was a ****** compu-carb!!

Gator · « **Reply #45 on:** April 25, 2008, 06:15:15 am »

i have previously replaced some buggered vacuum hose and had it running fine

dont know if cruise works its too undriveable to test

CJ-IROCZ · « **Reply #46 on:** April 25, 2008, 06:47:49 am »

Ryan ,I had the same problem when i fitted my new torque converyer. If the lock up isn't working properly the engine will stall as soon as its placed in gear.

the Torque converter?

Was gonna be my next thought too.....

Gator · « **Reply #48 on:** April 25, 2008, 02:58:20 pm »

right ho i was thinking along these lines myself

whats the fix lads ?

CJ-IROCZ · « **Reply #49 on:** April 25, 2008, 03:50:10 pm »

Could it be the lock up mechanism ?

I would go on this website www.bowtieoverdrives.com at around 8 tonight to speak to their online chat board experts. I dealt with Chandler and he is the dogs when it comes to 700R4. He will know if your sysptoms point towards a lock up problem
