car stalls out

way2fast · 07-10-2006, 06:49 AM

The engine dosent overheat at all, and i already thought of the cat and chopped it so it cant be that. there are no unnormal noises comming from the engine or tranny. the only thing that came up was a code for the neutral start switch or a/c switch. but after removing a little atf because it was high, and reseting the codes it went away. And I checked the neutral start switch and it is lined up perfectly. Other than that there are no codes stored.

Have you performed a cylinder compression test on the engine yet? If not I'd start there. Post your results and I will interpret them for you. Replaced the spark plugs/wires yet? I usually test spark plug wires before replacing but since there is a nice aftermarket for an 87-92 supra it would be worthwhile to just upgrade.

Order the Toyota Supra Repair Manual from your local Toyota dealership, should be around $100. Well worth every penny.

Okay I finally got around to a compression check and it seems as if #3,4, and 6 are shot they only came up to about 60 psi and #'s 1,2, and 5 were hitting 145 psi no problem. Not being an expert or anything but i guess i need to replace the rings. But my next question is meaning that 3 of the pistons are shot should I just replace those three or should i play it safe and spend the extra money on all six of them? Because i have never had to replace rings in any vehichle before are there anythings that i should consider when purchasing rings. Any info would be great thanks!

Check your intercooler and intercooler pipes and all the pipes after the turbo too. Somtimes they leak and its not apparent untill you start making some boost pressure. And yes i would say you need a rebuild and/or a new HG. Start saving now
