Car is a
'97 Beams, factory fitted, no modifications to the engine. I've got some videos I'll put up soon.Basically, this has been a problem that has started quite some time ago now and got worse and worse.
At first the car would just hesitate slightly under load, i.e. doing a third gear pull it would skip a little, like you had dirty fuel or something, or like it was misfiring. It would only happen maybe once or twice a month.Gradually it got worse and happened more and more often, over the course of six months or so
since 2013 maybe. It got worse and then began to affect the ability of the car to idle. Sometimes it will cut out on idle after an erratic period of varying revs. It cuts out very quietly. It was misfiring for sure now. The Check Engine Light was on periodically, on and off, during this time. It went off and has been since I (rather bravely) took the car on a long, 150mi run, during which it was surprisingly absolutely perfect! (Sunday June 30th). Previously the car had reported two error codes, Now it barely starts.
It splutters on start up, then will run. If you try and drive it, though, it's like it's in limp mode or something. One of the videos shows when I put my foot down it won't rev at all for a few seconds, then it will stutter up to 3000 odds. It's totally un-drivable now.My first thoughts were problems in the ignition system or dirty fuel.
So the fuel filter has been changed and the coil on plugs have also all been changed at quite some expense. It had a weepy rocker gasket so that was changed as well as the spark plug well gaskets. The beams of course doesn't have dizzy cap or rotor arm. The plugs are new. I also disassembled the entire intake system and cleaned out all the gunge up to the throttle body. I cleaned the MAF sensor. The car had error codes 34 and 41 stored, which are Turbocharger Pressure Signal and Throttle Position Sensor, weirdly. One of the Beams guys tells me Turbocharger Pressure Signal is ISCV related, and to clean ISCV.So the next thing I was going to change was Throttle Position Sensor, which is now on order from Toyota, as well as new screws to replace the ones which will doubtless have to be drilled out.
The only other thing I have heard is that the negative battery terminal is a bit loose in gripping even when tightened. I plan to clean the ISCV because it can't hurt and it's been suggested. I have noticed for the first time today that the exhaust has unburnt fuel in it, by the looks of things.Help!
