3SGE running like crap, massive let down for first drive

Post by CalMac »

First drive this afternoon - took it nice and easy to begin with thinking I'd give her a nice run before opening up (hasn't been properly driven in a year) and when I was confident the temperature was ok I gave it some beans only to discover that there were pretty much no beans! #-o

Also it then promptly decided to overheat when I got home and the 'TRD' rad cap (marked 1.3) began steaming :-s The coolant was only changed last week.. So I've stuck the OEM (marked 0.9) cap back on and that helped to maintain the temperature in the mid-range - I've ordered a new thermostat anyway just in case.

But the lack of power, I don't get. It sounds like a straight-piped V8, really burbly and sort of.. chuggy? But when I put my foot down it wheezed from 20 to 50 in about 10 seconds ](*,) Also it keeps stalling when I let off.

Drove it home like this, then took it out about an hour later and the exhaust note had changed to Jap car - performance was much more what I had expected, then reverted back to dull mode after about 5 minutes.

I've changed the oil and filter, changed coolant, Magnecor leads, Dizzy cap and rotor arm, Spark plugs, air filter, throroughly cleaned the TB and intake manifold, and it's got plenty of fuel.. Could it be a clogged fuel filter or knackered pump? Also I've read that it may be the coil pack or ignitor.

What on earth is going on? :(

£30 of super unleaded in last night (from the pump) hoping that would sort it, but no difference!

There were various dash lights on when I turned the ignition on (didn't want to start it as was late and my neighbours weren't pleased :lol:) Don't know if they'd go when the engine is started, I'll see at lunch.

The battery light has remained on constantly throughout a new alternator and several batteries though :-s

Have you checked your error codes?

See everyone talking about checking error codes all the time, but I have no idea how to :oops:

Don't I need diagnostic equipment or something?

It sounds like it's running on 3 out of 4 cylinders. Check your spark plugs all have a proper connection

The overheating issue is probably air trapped in the system. Theres a specific way of changing the coolant on these cars, its a pain but needs to be done that way.

Sorted the misfiring/3 cylinder issue - there's a loose connection in the injector wiring. I've temporarily cable-tied the black plastic surround into place and it's now running perfect :thumleft:

Still getting to the bottom of the overheating - so far I've found that there's no power going to the rad fans, although I've pulled the relays while checking with a voltmeter and none of them seemed to affect the operation of the fans! :-s I'm thinking the fuse box lid may relate to a different revision or something..

Once that's sorted at least I can get the alignment and tracking done, and the ever-deflating OS front tire #-o

Magnecors will be to blame! Stay away seems to be the advice.

Definitely Toyota.

The beams leads are coil on plug leads so a bit if a different case, but always always Toyota.

I just paid £336 for four cop leads and a gasket set...

Luckily I've got a set of almost new Toyota leads which I can try if I don't get anywhere when checking the injector wiring. Need a dizzy cap with 5mm terminals though, will have to be a blueprint for now as I only have 2 days left until Europe now!

Drove my KA to work this morning and it felt QUICK in comparison to my 2 :pale: lol

Yes its bad because they are a bit hit and miss. I've had mine on my 2 for 7k miles now and it still looks brand new and works perfectly. However, others arent so fortunate..

Going by the evidence of Youtube it would appear that the sound is a rod bearing which has gone wonky :lol: So I think a compression test is in order!

Now, I have a spare complete 3SGE sitting here.. same rev, import etc.

Is it at all viable for me to spend the evening pulling out the functional bearing or whatever it happens to be and swapping them? It can't be that difficult.. can it? :roll:

engine swap is probably a better idea mate :thumleft:
