Check engine light 25, 26 and 71.

OK, If I find out the gauge read very low then 33 psi, what should I do next things? And my car year 1995 had OBD 1. Do you know about the new scanner had both of OBD1/OBD2, is it reading live Data information from black box with car running warm?

Okay, Hmac300. I really say thank for more help, but not finishing at yet. There no more Check engine light, but engine still bad idle, also run smooth, weird life. Because I pull off EFI fuse to clear off code, snipe. I found out, that I pull off the EGR valve with copper pipe fitting remove, these part clog of EGR's connect lower right side of vacuum hose, it had alot carbon full clog. Wow, I cleaning hose with EGR Male connect tip. I will put back soon. Let see engine run smooth or not. I need help something more, text later.

This time, I'm going to clean all the parts of fuel injectors, EGR valve, cleaning whole fuel line delivery pipe and injectors as an assembly. Do you think to replace Fuel Pressure Regulator or cleaning spray carberator can, and air pressure blow.

Anyway, it look pretty bad shape of Toyota Camry, these very difficult of all connection plug falling parts in whole engine, it like turn hardend plantic plug and seal breaking so easly. Then I replace all new Denso Fuel Injector Connector Blitz Sard Toyota. And I already build the pipe with hose connect of air compressure, 20 psi and Fuel Cleaner Can to test the fuel injection, spray very well and clean good. It nothing wrong with fuel injection and fuel pressure regulater. I will put everthing back of fuel injection soon after order new 4 injection's o-ring seal kits, that really bad hardend o-rings. Maybe that where air leak intake in 4 fuel injection's o-ring leak and hardend.

Today, I finish, everything back on the engine to start the car, it seem not going be better, so far the fuel injection o-ring new and tight seal property on fuel assembly. I wonder why, this car not go up higher rpm for cold start engine, 2000 rpm. It still low rpm below 900 rpm idle at cold start and time to drive more then 30 minutes, still low idle same thing very bad misfire. Now, I have no good to get the fuel test gauge not fit of top fuel filter fitting. It not going to do anything to fit the fuel gauge. I am stuck anyway. Please give a change to figure out, what wrong with rpm and idle. I already change new idle control cost over $230.00. Japanese crazy thieve. I hate it.

Okay, I already clear out the codes from removed EFI fuse last night till morning. I check the Line from ECU terminal's wire of green/red line and green/yellow line to end of connection plug (Idle Control's plug terminal). And one Black/orange line had power 12 voltage. All wire just fine. I start the engine to drive on the road, more then 15 minutes. No new codes at yet and still bad idle stall many time after stop the traffic light, still very low idle rough. But it drive or race very good. It so wierd. Then I test scan on engine light, these light was said, Flashing, flashing, and over again flash light. My god, I already change ECU from Advance Auto Parts last second time few mouth ago. What the "Flashing mean, it bad ECU?"

Okay, I have a book owner's manual of import vehicle code reader, same you gave us the information code. It say, Flashing one per 1/2 second, it mean that normal. I surprised about the ECU code read work fine and normal. So, the engine Idle still misfire or rough. That reason, Camry stalled sometime stall again after stop traffic light. But it drive or race still good, so weird again. Anyway. I will check the compressor gauge and fuel pressure test too.

All right, I got read 41 ips fuel pressure gauge at engine off with jumper at B+ and FP test, Key on. And then remove jumper from B+ and FP test, remove the vacuum hose to the fuel regulator and plug end hose. Measure gauge read say, 39 ips at engine idle. And test again for reconnect hose back to fuel regulator, measure read 38 ips at engine idle. So, I think of fuel regulator come out not match in my book (Chilton's Manul Book).

I all ready got new idle control and cleaning Fuel Injection done.

I replaced new IAC from Advange Auto Parts and cleaning the throttle body with air blow and gas cleaner spray can. There no any new codes for engine running alot of hours so far. Do you think Fuel regulator bad? That I got my chilton book for test, it surpose be measure the fuel pressure at idle on 31-37 psi. I have read fuel pressure gauge say, over 38-39 psi. It too high, right. I try out the engine kick higher 2000 rpm, it reading the gauge say very low then 35 as possible, then I let the engine back to idle go up to read gauge say again over 38-39 psi. This book say, it must be idle for 31-37 psi. Okay, then I check each compressure gauge test read, 180 psi (1), 180 psi (2), 179 psi (3), 181 psi (4) cylinder. It hold pressure more then 5 min. All stay up very good cylinder.
