Silvertop AE101 problems

[Dazed&Confused]

Hi there,

trying to fix a mate of mines ae101. we cannot figure out the problem.
it is not idling smoothly, not revving to redline, the engine has no power and the engine check light is on. what could be causing this?

it happened suddenly, and he thinks it came right for a little bit when the engine check light turned off for a couple of minutes.

going to change fuel filter and check compression. any other ideas? AFM?

thanks in advance.

I had a problem with mine- it never reved to redline. Had something to do with the ecu and afm. Had to reset codes on the ecu, as afm unplugged sent dodgy code to ecu or something

[rollaholic]

if the check engine light is on, your first port of call should be checking the codes! i believe theres a how-to in the FAQ, or if you search it will have been detailed many a time.

with that info it should be obvious whats wrong, but it does sound like an AFM problem

[johndoe1025]

worst case maybe vvt, but as everyone else has said, check codes, more than likely afm

Leaky caps in the ECU possibly

[Mr Revhead]

definitely check the codes
do that first

ecus are know to die on these

My bet would be ECU.


I have a repaired one that I will either sell or do exchange on if you find out that it is that.

warmed it up, shorted e1 ant te1, turned ignition on, but the c.e.l didn't flash?

Try again, I had to clean the green cap off my terminals, but it should definitely flash, even if no codes stored.

[.:O4AGTZ:.]

sounds like it went into some kind of limp mode. my gtz did that too but the cause of it was the caps in the ecu melting which i have heard is nearly a common problem. engine check light was on but no codes came up. is this a common problem on silvertops as well does anyone know?

[Mr Revhead]

yes it is
faulty ecu running real bad and no check codes

[Adamal]

Its probably due to the fact that the spark plugs were all busted up, and the leads so worn that they were arcing against the cam covers!

Let us know how she runs with those new leads and plugs, Lowndsy!

[Dazed&Confused]

the leads, plugs, rotor and cap were replaced with no results. starts better however. still have engine light and wont rev past 6000.

took it for a drive, and the engine light went off and it was back to normal for about 30 seconds! it must be the ecu if it is doing this randomly?

anyway its in toyotas hands now to see if they have anything to say about it.
but we are going on the ecu being buggered. so now, has anyone got a silvertop ecu in auckland that we can try? and then buy if it fixes the problem?

oh and p.s, someone mentioned the variable valve timing could be the problem? meaning the engines dropped the pulley?

[Mr Revhead]

does not sound like faulty VVT to me

[Dazed&Confused]

doesnt not or does not

[Adamal]

VVT works on the oil pressure doesn't it? That'd explain why it comes right after driving for a bit, pressure comes back up. Maybe the oil pump is stuffed?

[Dazed&Confused]

nah that couldn't be right. because when it came right it died shortly after. and we sure as hell kept oil pressure up when it came right

[Adamal]

Bro, just drop in a 3SFE from a Corona man.

[Mr Revhead]

doesnt not or does not

the latter!
