or the resistors where defective.....you gun it and goto 8K...and run super-lean...PING goes the motor...retry the compression test and get back to us!

sounds bad :(

i know the motor is blown. i already ordered the rebuild kit and new housings. i want to know why it ran a little rough after i put in the low impedence injectors (with resistors) but when i swapped back to the stock high impedence injectors (with no resistors) the car won't idle, backfires real bad and won't hold an idle. i need to be able to drive it to the place im doing the work on it.

who knows, it's kindof hard to tell you exactly what the cause of runnig rough is when you have a known blown engine, this can't be terribly consistent, who knows if the state of your engine is the same as before? If you have low compression, something broke, something could be eating away at your housings, or worse... I definately wouldnt be running an engine that I knew was blown, it would be either getting towed to the person that would be doing the work or getting disassembled after being pushed into the garage. By running it you are probably just causing more damage and a more expensive rebuild.

it is just low compression. i drove it for a few days including an hour trip. i just need to be able to drive it about 15 mins away. i just don't see how the car just sitting for a week it could have gotten that much worse
