G'day all, been a while since i posted, finally got the tp on the road, but now having some issues, getting up to speed in a hurry ( putting foot down half way at least if not a little more ) for instance from stand still to 60 the old girl jerks pretty bad ( revs keep rising and falling ) until she gets to about 60/65. we checked the diaphragm ( chucked it in pot of boiling water to make sure its working ), no problems there, checked timing, all good there also, not sure what to check next, fuel? or cooling?

Also going to be throwing on another rocker cover in the next few days, any tips about tension on the 2 bolts, or just firm ( not too tight that they crack the cover ) ( reason for replacing, keeper was knocked off accidentally when checking timing etc to find the pre-mentioned problem )...

Cheers :)

Hi, rocker cover bolts tighten to 5-7Nm, I think I read somewhere over tightening distorts the shafts.

Yes, 5-7nm and that is very light, so go easy on them. Also, be gentle with the two bolts that hold the plastic guard for the water pump pulley. In particular, if you overtighten the one on the side, you can easily break the lug off the rocker cover. I've broken two rocker covers that way. On one, the lug took a big chunk of alloy with it, leaving a hole through the rocker cover. On the other, the lug broke off but only took a small chunk from the surface, so didn't leave a hole.

Yours is a carby TP, right? Check your fuel filter first. If it is not that, your charcoal canister may have deteriorated and let carbon granules get into the carby. If that's the case, it will get worse. See my threads here: http://www.aussiemagna.com/forums/showthread.php?t=74352 and here: http://www.aussiemagna.com/forums/showthread.php?t=74309 Note that in my case the carbon granules didn't get into the fuel tank, so the fuel filter didn't stop them. There's a hose from the carby vent valve to the charcoal canister. The carbon granules came up through there and presumably got in through the vent valve. When reading the threads linked above, bear in mind that at first we didn't know the cause, so got side-tracked checking the fuel pump etc.

Ok thanks for that about to get stuck into it, running efi coldamus. going to check over the fuel rail and injectors etc, just dumbfounded at the moment as its only just started happening in the last couple weeks, haven't done much driving or gone anywhere indecent, nothings been changed. Problem with the rocker cover is the keeper near the plastic guard got knocked clean off. If there were any mechs close enough i'd drop by so most work have to do myself...Best get on with it, get this rocker cover sorted first, then try do some troubleshooting. Cheers for the advice

I bet the jerking eases as soon as you lift the throttle. Sounds like a weak spark, check plugs, leads, distributor cap centre button for wear and burning. Also, the coil and power transistor on my TP gave these symptoms. Get a matching coil & power transistor from a wreckers.

What Diaphram did you check

after checking all the sparking parts ... if no better post again

the rocker cover bolts - if too tight -can crack the cam bearing caps -the bolts go into

ok so its a TP sedan EFI
push button start
double barrel shotgun tip
did you do the digi dash conversion ?

To do .
three diamond custom bonnet scoop...
.( Make a polly styrene shape then use fiberglass )

Yeah letting the throttle off drops the rpm and she drops into next gear, got some spare parts off tn still such as dizzy cap, leads, spark plugs etc. hoping its something more simple such as that, and not a gear box problem. Got the r\c bolts sorted tightened to 5nm no probs.

no buff, no digi dash yet, considering it, as for diaphragm.....thermostat is what i meant..and yes am going to look at getting a block of foam/poly and carve it first, see how that goes for starters

nope not a gearbox problem

could be the pedal switch causing the problem ... it can be adjusted and tested

then the TPS ... it can be adjusted

Did not think of tps, good thinking buff.....it's still running, but poorly still, so am awaiting the arrival of an obd tool, now about to go hunt for where to plug it in. i know vr commodores are right near the bottom of the steering column, already done one of those using paper clip, but for the tp am guessing its near the fuse box under the dash, or near the left strut...

obd2 scanner..... connector 8 required for the first gen
http://codes.rennacs.com/Petrol-Engine/Japanese-Korean/Mitsubishi-Engines.php

second gen-- obd2 diagnostic scanner ....plug in is near the internal fuse box D/Side

diagnostic plug first gen I know of above the glove box gives you some auto and efi information
the round one near the coil in the engine bay for timing

Ok the connector 8 on that page is a 10 pin connector, at minimum on ebay all I can seem to find is 12 pin...

If you're talking about the diagnostic socket, you don't need to buy a matching plug, just push your multimeter probes into the appropriate holes. That's assuming you're using a multimeter to read the codes. (N.B.: it must be an analogue meter - codes are impossible to read on a digital meter).

there is no scanner for these first Gens

that plug is for the tranny faults ..the EFI is in the engine bay near the dissy

its a test light --- for the best result cheap as in dick smith or similar ..contacts making a light bulb circuit

..just Go by flashes --- long flash then quick flash etc

I have the codes..... there are 48 possibles from the glovebox plug ==4 pages

ok cool, found the efi plug, yet to check the glove box one. got both analog and digital multimeters, and a voltmeter kicking around somewhere also, test light is sitting in the glovebox. will see how i get on today. worst case scenario there's a mobile mechanic coming out this way in a few weeks, if i can't sort it by then, will get him over to suss it out, cheers all
