Hi Bill,

With all that fuel I'd jump right in there with Kentucky on a malfunctioning cold start injector.

Problem is, your 88 doesn't have one. Taking its place, though, is a function in the brain that gets your four service injectors dumping raw fuel in when it senses the engine temperature is like Northern Alberta in January.

Is it getting lousy mileage? Stink of fuel even when its idling?

There's a little blue sensor under intake port #3 that will break off or die open-circuited and do exactly that. It is hard to see, much less replace, but you can test it from the comfort of the car's interior, if you pull the plug off the brain (ECU) behind the passenger's right foot.

Measure the resistance from pin 2 to ground on the connector. With three 240's, you certainly must have a Bentley or Haynes to give you more details on that plug and a chart to determine what the resistance reading should be, but if not, post back, we can dig it up.

Comes time to change it, use a deep-well 19mm socket on a 10" extension. Have the new one ready so you're not losing too much coolant while swapping them. Here's a new one next to one of my broken ones.
