Engine cutting out while driving

Post by Bala8542 »

I have a MR2 Rev 2. Recently it started emitting black smoke and subsequently the engine cut out while driving in the 5th gear. I replaced the lambda sensor which seems to have fixed the black smoke from exhaust however the engine still keeps cutting out while driving.

The weird thing is that it immediately starts back up when I turn the ignition off for 15-30 secs.

Today I also noticed that briefly the rpm needle bounced all the way to the redline and dropped back while I was coasting. Not sure where to start. Car has new battery fitted a month ago. Is this an alternator or a coil pack issue ?

I bridged the E1 and TE1 connections in the diagnostics port but the CEL is just solid and doesn’t blink as it’s supposed to.

Are you sure you are getting a proper connection with the link ? make sure there's no corrosion on the terminals of the diagnostic connector, what are you using for a link ?
There's something far wrong if the CEL stays solid, may indicate a faulty ECU

I used a paper clip and then a piece of copper wire. Tried to push it in as much as possible but the result is the same. It won’t pulse. Even more weird was that last night when I started the car the CEL dimmed and then went off and remained off. It’s now doing that every time I start the car. It dims and then goes completely off.

Every time just before the car stalls the engine coughs and the RPM needle flickers and bounces like crazy and then comes to 0.

Was able to drive 20 miles away to my friends garage. Stalled few times in the first 5 mins but started right back up every time and once on the run it drove all the way. Stalled again when I pulled into his driveway.
