Car Forum / Chevrolet / Chevrolet Corvette / May 200489 Idling Problem Found
Hi everyone Finally the problem is solved. Results, Faulty injector, #3. For future causes, is there a specific way to tell if an injector is working or not? Thanks for all your help... Dan 89 Coupe Blk on Blk yes there is a way to tell, but it is pretty labor intensive! you have to pull all of the injectors and fuel rails, pressurize the system, then use a fuel injection tester (snap-on has them) to turn them on at various rate and look at the flow pattern and amounts sprayed. it really is a job for a professional. greg >Hi everyone > [quoted text clipped - 5 lines] >Dan >89 Coupe Blk on Blk Thanks Dan > yes there is a way to tell, but it is pretty labor intensive! you have > to pull all of the injectors and fuel rails, pressurize the system, [quoted text clipped - 11 lines] > >Dan > >89 Coupe Blk on Blk >Hi everyone > [quoted text clipped - 5 lines] >Dan >89 Coupe Blk on Blk Makes sense. I wound up with 5 (that's right, 5) crappy injectors in various stages of pooping out. Car ran pretty good, but wouldn't smog...alternately lean and rich. My mechanic finally yanked the rails and injectors, pressurized the whole rig, and looked at the spray patterns. Wound up buying all new injectors. Sucker runs like a scalded dog. Go figure.

How much did you get smoked by the mechanic ? By the way, here's an old post (couple of years ago) from this news group about injectors (no opinion express or implied by me): ============================================= Replacing injectors on an '85 (possibly other years) I know you're not gonna like this, but you can replace your whole set of eight injectors (24lb/hr injs. on an 85) for the price of one from GM. FORD motorsport 24# injectors for $169 a set! Pick up a copy, better yet, write down the phone number out of a page of a mustang magazine at your local store. ( You don't actually want to *BUY* a mustang mag... ;-) Look for 24# Ford MotorSport injectors. Price will range from $169 ~ $209 for a set! I have an '85 and replaced mine after 35,000 miles and *wow* what a difference. The car had a much smoother idle! Turned my "lumpy" cam into a tame one.

As for the car, it runs nice now. It still has the natural roughness, but my body doesn't shake from side to side anymore. I got clipped about 200 for the whole job, but would a Ford injector actually work in a Corvette? Sounds pretty interesting....If thats the case, I'll pick up a whole set and just have them all replaced next time I run into the same problem.
