Hello, I do have some cheap Autozone brand wires on the car. I replaced the plugs with Basic NGK models, and filled up tank with High Octane Gas. I have been putting a transmission in 03 Camry (Daily Driver), I have been driving Legacy everyday for last 3 weeks. I'm going to order some NGK Wires. I couldn't find them locally. I got really lucky, and finally found a 92 legacy being parted out on Craigs List. I got 92 ECU, Fuel Rails, and Red Top Injectors. I'm familiar with reading diagnostic codes. Check Engine Light is Off. Will there still be codes in active mode, if CEL is Off? I thought I needed a CEL light On to use active mode, but I'm pretty new at diagnosing OBD1 cars. Thanks!

Hello, I have a 1991 Legacy Wagon, Automatic Trans 2.2L 140,000 miles This car is not my daily driver. It belonged to my Dad who was a Mechanic, and I inherited it in 2001. I like to drive it for sentimental reasons, and it's awesome for the places I go Mountain biking. I try to stay on top of everything, and the Car was running great, but had a problem with bad Fuel Injector last summer. This was 3rd injector that failed, and like an idiot, I thought buying a complete set of Bostech refurbished Injectors would be a smart idea. I replaced all 4 injectors, and the car wouldn't run properly with replacement injectors. It would start, but would bog down when I stepped on gas, and wouldn't shift at correct points. I had posted several times on this site about the problem, and everyone was very helpful sorting it out. I eventually swapped injectors with combination of black and grey from local salvage yard. Car started right up, and seemed to run fine. The car is now difficult to start. I have to crank the engine, and work gas pedal. It seems to run fine, but not as smooth as I remember. It also seems like it might not be shifting at the optimum shift points. I replaced transmission a couple of years ago with low mileage used transmission. I'm not getting a CEL. I tried replacing spark plugs, and plug wires are less than 1 year old. I have swapped MAF, and igniter. Tested Fuel Pressure. I have read hundreds of posts on this forum, and Legacy BBS, but I'm not sure what steps to take to remedy problem. I know car was shifting at weird places with Bosetech Replacement injectors, but I'm not sure which sensor sends info to ECM about shifting. My gut instinct would be this might be culprit. I live in Northern Ky,/Cincinnati area. I never see these cars at local salvage yards. I'm not sure if they weren't popular in this area, or if they were all junked a long time ago. I don't have finances to buy all new sensors, and parts to troubleshoot. I'm completely grabbing at straws, and would be open to any ideas.

Problem Solved! Fuel Injector Problems. Bosetech Injectors, they look correct with grey tops, but don't work properly. Thanks for all the help. I did check Vacuum and Fuel Pressure along the way.

I checked ECU codes with black connectors, and didn't recieve any codes. I tried the green connectors and followed instructions driving car, I got code 32 which is O2 sensor. I'm still confused why I wouldn't get a regular CEL if there are problems with O2 sensor. I also stopped at Harbor Freight, and bought Vacuum Gauge and Fuel Pump tester.

The injectors look correct. The 3 types that I'm aware of for 1991 Legacy: Black top - Manual Trans Non-Turbo, Grey top - Auto Trans - Non-Turbo, and Red top - Turbo Models. The replacement injectors are grey, and look exactly like the originals. I'm going to try and pull the ECU Codes. I never cleared them, and I'm not sure if they erase after having battery unplugged, for extended period. The car was hard to start after I replaced the injectors because some fuel had seeped into cylindrers. It smoked like crazy when I first started it, and fouled the plugs. I wonder if I could have fouled the O2 sensor, or ruined the Cat. I'm just reaching for straws trying to determine what to check.

It seems like it's running rich, and bogging down. I don't have any CEL. I didn't try the blink code... because I thought I had to have CEL, but I'm not sure. I drove it about 50 miles. It is slow to get up to speed, but will cruise at 80mph. I had to go up a short steep hill, and it didn't think I was going to make it. I can buy a vacuum gauge, I don't know how to use it, but will try to figure it out. It has 124,000 miles on it, and Timing belt was done at 98,000. What types of problems would pressure regulator or fuel pump cause? Do those things throw CEL? This was my Dad's care, and I inherited it in 2001. The transmission went out in 2011, and it took me a year and two transmission to get it back o nthe road. I think sitting was bad for it, but it was really hard for me to find a transmission in the Cincinnati Area.

Where can I get ithe injectors tested? I have never done that before. Thanks for reply. This problem is very frustrating. Lou

I need some suggestions about getting my 1991 legacy wagon 122,000 Miles, running properly. Last Sunday I was driving the car, and CEL came on. Car started running very rough. I knew it was a bad Fuel injector. I had a couple of bad injectors over the last year, and I had used a few I got from junkyard. I was surprised to find the price of bostech injectors had gone down. I ordered 4 new injectors and replaced them all with new injectors. The car was very difficult to star, after changing injectors, and I realized it was flooded. I got it started, but it was running rough, and smoked a lot. I checked plugs and they were fouled. I replaced plugs, but it's still running very rough. It runs just fine in my neighborhood, at slow speeds when I'm getting on highway, If I step on the gas, it just seems to bog down, and not accelerate. If I very gently press the gas, it will gradually get up to speed, but doesn't seem to shift at correct times. It was running great last week before these problems started. The lack of CEL leaves me guessing. I started to wonder if the fuel injectors I purchased are teh problem? I did notice the new injectors had a round O ring on bottom, and I think the stock In jectors have a flat rubber gasket? I'm open to any suggestions. Lou
