Ignition bug (Page 2/2)

Went by my mechanic to check on the heads, told him of the trubbles I was having. He said dont bring it here lol. I finally figured it out, noticed a very slight change in running w the map unplugged this morning. Got a new one and it didnt fit the connector. Then I noticed it was used. Then I had the bright idea for chits n giggles to throw the 88 computer back on and see if that made any diff. I was using the 88 harness which required the 88 map, and it was an easy enuf experiment. Installed it, runs like a champ even w the turbo prom. Little miss but the car hasnt been driven so hopefully that goes away w a long trouble free cruise. Idled around 1500 for about 10 mins, then dropped to a hunting idle of 1k-900rpms. Again thanks for all the replies!

If you wanna clean your injectors, you can pull them out and hose clamp a couple feet of vinyl clear tubing onto them one at a time, and hose clamp a compressor fitting at the other end of the tubing. Then fill the tube with carb and choke cleaner, hook it up to a compressor regulated down to like 50psi, then apply power in short intervals to the pins on the injector and it will spray the cleaning fluid through them and you will quickly see them return to their original spray pattern. Done this many times with great success on different cars. I use the clear tubing because you can see how full of cleaning fluid it is. It’s like $5 of parts from home depot.

Thats pretty damn cool, never heard of that before. Pretty sure the injectors are original to the motor. Im on the hunt for a stock 88 ecm to see if that clears up the idle, could just need to drive it lol. Gonna swap it out soon anyways, this setup will just be fer emissions testing

I feel ya but it is a nice to know trick for any motor, anytime I pull my wrx motor out (maybe every 50K miles lol Subaru life) I give the injectors a cleaning, it is a 15 min job once you have a setup made, and you'd be shocked how fast the spray pattern starts degrading. Good way to clean your L67 injectors before swapping that in, makes it run crispy.
