Surging issue

[FallenAngel]

Hey guys,

Got an issue with the dc2r where it surges suddenly when driving.

- It occurs when you accel at any gear.
- The surge occurs when you have your foot on the accelerator.
- When it happens it loses power until you release the accelerator
- Once you release the accelerator then accel again its ok.

Basically thats whats happening, and i'm not sure whats going on.
I've used injector cleaner in the fuel and have been using premium all the time.

Any ideas guys?
Thanks in advance

It could be related to the TPS.Here's how you calibrate the voltage on the TPS:

I would just check to make sure the timing is in the correct position too,because that too can cause surging/hesitation:

thanks for the quick reply.

I'll have a look into it

No worries,keep us posted aye!

Had a look into it, and it doesn't seem to be the problem...

Its also now had started to stall sometimes when coming to a stop maybe like once or twice in a hr's trip? And when you start the engine again it seems to sound like a wrx (if you get what i mean). Seems like its only running on 3 cylinders but when you re-start the engine again its fine....

Whilst cruising, i can hear the exhaust backfire occasionally, in which i assume i'm running a tad rich....

I'm planning to change the fuel filter and the sparks tonight and i'll see how that goes. but other than that has anyone got any ideas on this?

i would have said try changing the spark plugs, which you are doing, and see if it improves the problem
another possibility is that one of the ignition leads/an ignition coil is on its way out. is the power loss problem worse on a cold start?

[FallenAngel]

Literally happens randomly, cold or hot. Occurs more often when driving as the engine is warmer. I might pick up a set of ignition leads if this fails.

I'm just wondering is there anything else i'm sorta missing

[beeza]

The ICM - Ignition Control Module in the distributor causes the car to Konk out randomly,when it starts to go.I would check that next.

Sounds like an ignition issue and good advise so far.

Also try measuring the resistance of your leads to see what it is (and how they differ).

When ya main fuel relay starts to go,what are the signs?

intermittent starting problem on hot days. the car will crank but the engine will not start as the fuel pump is not energised.

Gotcha!
