R33 Total Loss Of Power

[i2icho]

Hey all ill start from the start,

Late last year i was defected for a FMIC so i returned my 33 back to stock SMIC, i also took my car to a pannel beaters to get the I/C pipe hole (bellow the watter bottle) welded back up, Ever since i have had my car back from them gradually a problem started to arise,

I would be driving down the road and all of a suddern i would loose all power to the wheels the revs would stay at the same RPM but with no power a second later it would come back on, it would jerk me around the car, make me look like a total fool who cant drive lol.

Reading thou the forums i found a simular problem with someones R32 it was with the AFM,

So this is what i have done to try fix the problem

-Taken out AFM totally cleaned contact points, Element in the middle (with contact cleaner)

-Checked I/C pipping for leakes half a dozen times.

-changed oil

-checked plugs coil covers.

-cleaned throttle body

Did all of the above last weekend,Everything was running smooth up until last night Was driving home from work,going from 2nd gear to 3rd and the problem happened again the first time in 5 days, which was good compared to it happening everyday.

Still very dissapointed thinking the problem had been fixed,

The problem happens within 1-2 mins of car being turned on, Could this be a alarm/imm problem?

Its very very frustrating would like to get to the bottom of it without forking out for a new Fuel pump and AFM.

Can anybody shed some light?

It could be any number of things, what other mods have been done to the car? Was it tuned for the fmic and did you get it tuned after? Have you tried resetting the ECU (disconnect battery for a min)? If they welded on the car without disconnecting the battery it could of disturbed any number of electrical components.

are the battery teminals in good condition and tight?

Im pretty sure they didnt disconnect the battery when they used the Welder, The place i took it too was shonky as all get out it should of sent alarm bells ringing.

The ECU wasnt tuned for the FMIC and i havnt reset the ECU since putting back the SMIC,

Other mods that were reversed was a Manual boost controller (by passing the Boost Solenoid) I had to reconect and replace Vacuum hose that was taken out to hook the Solenoid back up, Its all connect correctly thou so i cant see how that could be causing a problem.

just re-set the ecu

disconnect either battery terminal, stamp on the brakes and turn the lights on and off

then leave for 10 mins to an hour

reconnect and let idle till warm and go for a drive
