Do you think you'd still make the adapters for aftermarket gauges to fit in the stock cluster?

No codes. Here's pictures of the plugs. Replacing them with NGK double platinums tomorrow. These have roughly 3000 miles on them, NGK Platinums. I replaced my spark plug wire set due to one or two of the wires shorting out, when i first encountered my misfire. Currently thinking that the...

Fuel Pressure currently unknown, I will be picking up a gauge ASAP. It takes about 5-10 seconds to catch when turning over, especially when sitting overnight. When it does catch, it idles perfectly with no misses or stumbles at all. CPS is in good condition, wires are near perfect under the...

My apologies, I thought I was in the 7mgte technical section.

Having an intermittent misfire with my 1989 7mgte r154. Car was originally auto and manual swapped about a 2 months ago. The car is having a miss and stumble under load, and while it is doing this the car is leaning out. Its a stumble, to the point where the car jerks slightly. It is not hitting...

Quick update on the supra.. Got everything back together on the supra. Replaced a few cracked couplers on the intercooler piping. Car did start, but is doing the same thing. Decided to mess around with the TPS connector and I found that if I held it a certain way, the car would run great. I...

Decided to pull the entire engine harness. I'm going to test each wire and rewire the knock sensors into the loom. I also pulled off the turbo and rebuilt it Saturday night. I didn't realize how bad the turbo was until I pulled off the hot side of the intercooler piping and found about a half...

Alright, new lexus afm came in the mail, no dice. Car is still doing the same thing... I'm going to do the knock sensor rewire and go from there. All of the injectors are firing, I can feel them with a screwdriver. Each plug is getting spark. Pulled one plug and it was extremely black from...

UPDATE: At idle when warm the air fuel ratio is about 11. When I barely give it any throttle it accelerates slowly but sounds good and air fuel is about 14-15. However when it starts running rough the air fuel ratio is about 17-18. Decided to pull off the afm and inspect some lines. Found that...

So looks like I'll be doing the knock sensor rewire, and try swapping AFMs with a friend! We shall see if this fixes my issue.

It starts within 4 seconds of cranking, firing on a few cylinders then it catches up. UPDATE: Finally got a check engine light, and pulled the codes. Code 24: intake air temp Code 31: afm Code 52: knock sensor Where should I start first?

Car struggles to start and needs some throttle to keep idling. Once "warm" it idles OK. I will check out the connection at the sender and the sender itself. On the thermostat housing the only part disconnected is the A/C, which makes sense as the A/C does not have a belt on it currently...

Yes, the wire to the top sender is bare and wrapped around the tip of the sending unit.. Will correct that. My next question is that there are two wires (see pic 2 of first gallery) near the CPS that are cut. Any idea which one goes to the sending unit? Or do the both attach to a plug? ALSO...

Update: I tested the TPS resistance and it checked out per the TSRM. Now I'm going to check the CPS timing

No codes right now.. The car is teasing me. It runs great for a second or two, then will return to the usual problems. I have tries unplugging the TPS and the lexus AFM(same as maf?). When plugging the afm back in the idle increases for a second, then dies down. Also, My temp gauge is not...

I already bypassed the connector itself. Is it possible that the timing belt slipped at all? Is that common? Looks like I'm going to need to invest in a timing light!

So, the supra runs! It was running great, I let it idle for about 30 mins to warm up, then took it about a mile away to fill up the tank with gas. Made it back to my neighborhood, and now the car is running really roughly. It dies as soon as I give it any throttle. I'm going to check the timing...

Absolutely no clue. I know they are 550 injectors according to the previous owner, but have no markings on them. Traced the plugs for each injector and they were spliced into the wiring. I screwed around with some carb cleaner and wires last night and somehow manages to get the other 4 injectors...

UPDATE: While everything was apart, I decided to test each injector to see if they would pop. 2/6 injectors worked as they should. The other 4 did not fire at all.. Looks like I have found my problem!

I have not looked through the TSRM.. I know, shame on me. Anyways, tonight I switched coil packs with a running car, no dice. Noticed a sparking under the intake manifold, and thought that it could have been the reason for my intake fire while using starter fluid... Pulled the intake, injector...
