Thaaannkk you ^ it was rings and cylinder wall

So update, the misfire got so bad that I could've the car anymore because it almost stalls at lights and idles at 400rpm. So I stop driving it and began work, replaced the injectors with cleaned and flowed ones and a new fuel filter as the old one was very dirty, I've checked and cleaned the...

So I may have so internal issues valves, rings, cylinder wall gazed or damage, I'm not saying head gasket though:nono:. But started pulling out spark wires while the engine was running, Cylinder one had no effect when pulled. When the engine is revved plugged and unplugged made a difference...

Okay so I did a compression test, everything is still within the tsrm spec, Cylinder one may have a bad valve or rings? pulled the spark plug wire and injector misfire is still there 1. 135 2. 170 3. 160 4. 150 5. 170 6. 160

Yea, was going make a separate switch for it but went this method, and thats what battery switches are for. I still don't think its a head gasket, because I've experienced two bhg's on two NA motors and the symptoms not are the same in motor vacuum, When I checked the spark plugs I also looked...

I don't have to, I had some issues with the fuel relay, and I couldn't locate it on the cressida chassis at the time, I grounded one of the wires from the wire looms to stay on constantly at 12v when in On mode, 13-14v when engine is running. If you listen closely for the first few seconds of...

No, I do not have a fuel pressure gauge, I'll check that the pressure regulator is working properly, I can hear fuel rushing through the fuel rail when pump is on, though its been doing that since the beginning before I had this problem. Fuel pump is working normal. Edit: Can it be a bad...

I just tested the cold start injector for ohms and under startup fuel pressure it doesn't stay open or leak. Still having the misfire on startup

I’m calling this misfire an odd one because I’ve have search varies forums for this type of symptom. I have cressida rebuild swap 7mgte with about 12,000 miles on it been running great until last week, it starting getting this weird misfire. It only occurs during cold start and...

Heres all the info http://suprasonic.org/lexusriemer/lexusnotes.html

Is getting 17-18mpg normal 260 miles per tank mx83 cressida same weight as a supra 7mgte stock only 6000 miles on it with intake, 2.5 intercooling, big intercooler, 3" exhaust but 2in downpipe :( w58 trans, 3.91 final gear, and 215/60/15 tires

I have rebuild 7mgte with about 3k miles on it, with intercooling, intake and exhaust upgrades as well, and the compression ratio has been lowered a bit because I'm using 1.6 mhg. I'm borrowing a friends actron Advance analyzer with 0 to 60 advance dial. I was wondering how do I use this to...

Thats why I stayed 7m too then theres this, duane beat me to it...by a couple years lol http://www.supraforums.com/forum/showthread.php?622617-Duane-in-Import-Tuner/page2 Hey compton maybe we can both build high 7ms, I'll be getting another engine soon

^ He owns a race truck,

Am I doing this right? following the trsm

Hey Compton call if you need any help, but First make sure you find a good condition block and head, not like mines lol, but the first thing to do is to find the ingredients to the power you want. Know the 7m specs such as the bottom end and head, such as the pistons, and rods don't forget the...

Piston slap? I got that when I first started my car, the machine shop screwed up on that

Okay I will go back to the spark plugs I started with, and recalibrat the tps, also, will a knock cause the engine to run sluggish if broken? I have a auto ecu but I'm manual

Okay now I have a code 51, and 52 because my knock sensor broke, but the other one has something to do with the tps

Okay I checked the grounds the ecu getting power at all times, the misfire is weird, on cold starts It idles fine with no hiccups, but when it gets warm to normal temp it misses badly that I can feel it through the whole car and out the exhaust. this all didn't happen until I changed the spark...
