You might want to check a few small things on your own Posted by RS [Email] ![]() ![]() ![]() In Reply to: SPG dying..., Cody, Wed, 18 Dec 2002 19:12:30 Members do not see ads below this line. - Help Keep This Site Online - Signup |
AMM is a good possibility, but check some of the cheap and easy stuff first. Justin is absolutely right about the ECU - LH 2.2 ECUs are pretty simple-minded compared to the later ones:
How long ago were the spark plugs changed? If they're worn to the point that the gaps are too large, you'll get missing and jerky acceleration.
Bad spark plug wires, cap, and rotor can cause misfiring under load.
Take a look at the connector to the Hall Effect Sensor on the side of the distributor. They tend to become brittle after a decade or so of turbo heat. If you wiggle the connector while the engine is running and the engine stops, you have one possible culprit, especially if the front motor mount is weak. (WHen you accelerate, the front of the engine can rise, the wires on the connector get tugged and ignition stops, the front of the engine drops, connection is re-established, and the cycle continues until you let off the gas.)
Take a look at the rubber boots that hold the turbo ducting to the AMM, turbo, intercooler, and throttle body. If the hose clamps are loose or one of the boots has a small split in it (especially the ones downstream of the turbo) you can get very jerky acceleration.
