#22 of 62 Re: Intake manifolds [imidazol97] by 17thabn Mar 06, 2009 (5:32 pm)
Replying to: imidazol97 (Mar 06, 2009 5:35 am) The issue of the class action suit,if there wasn't one there should have been one because of the millions of cars from GM fron 95-98 didn't have the "Redesigned" plenum and smaller tube.That took anywhere from 4 to 6 years to show up.What about all the cost to the owners of those cars??If the plenum on your car is the ORGINAL, it has the month,date,and year on it when it was made.The new plenums do no have the date of manufacture on them. So if it was made 95-98 you got a burner.The only thing I was trying to do was to inform the little guy about repairing his car without getting shafted by cost of this repair.So you acknowledge it was a design flaw.Great.Have you changed yours yet??Or do you work for GM??

The car has been dying; it spent 4 days at one garag & he could not find anything he suggested another garage with more computer technology. Spent 5 days there they replaced the Mass air flow sensor picked up car drove it about 20 miles and the car started dying again. It will start back up may run a little while or may die immediately. It kind of back fires when it starts back up. Of course this happened after the garage had closed and it is closed on Saturdays. A new fuel pump has been put on the car; new plugs etc. Can someone give me an idea what this could be. It cost $311. today and the car and I will be there first thing Monday morning. thanks, DC Replies to this message: 17thabn (Mar 07, 2009 5:18 am) djc7 (Mar 07, 2009 6:12 am) imidazol97 (Mar 07, 2009 12:14 pm)

Replying to: djc7 (Mar 06, 2009 6:45 pm) I would replace the fuel filter and then the fuel pressure regulator.Probably $150. Replies to this message: djc7 (Mar 07, 2009 6:12 am)

Replying to: 17thabn (Mar 07, 2009 5:18 am) Thanks, but the fuel regulartor and fuel filter has replaced twice; the regulator was under warranty so made them replace it since it was acting like it was not getting gas and then replaced the filter again but it was not stopped up that time either.

Replying to: djc7 (Mar 06, 2009 6:45 pm) I don't know much about the earlier engines before 1992. I do recall MAF sensor problems caused many difficulties or something like that. I believe a test was tapping ont he MAF sensor with a screwdriver handle and if it made the engine skip or be uneven, the MAF was a problem.   Yours could be connections to the spark system and coils Could be fuel pressure.   You need to have a test spark plug and when it kicks out put a spark plug on one wire and lay it on the metal part of the motor. Have someone crank the motor and see if it has spark at the beginning before it fires.   If you can put a fuel pressure gauge on the car and drive it and watch to see if the fuel pressure drops when it stalls would be a big help. Duct tape the gauge to the windshield. The replacement fuel pump may be giving problems. The Delco replacements are best. My garage would only use a Delco because they had many return problems with other brands.   Crankshaft position sensors are a popular replacement item--not that we like doing things just because they're popular, but it's something to watch. The fact the car starts right back up after stalling makes it a problem to troubleshoot. The backfire doesn't help me much.

#29 of 62 LeSabre oil leak... by vanderbar Mar 11, 2009 (5:05 am)
I have a 93 LeSabre, 3.8, 145K miles. Yesterday I just took a look to the oil level, and found fresh, more or less concentric oil leak signs under the cylinder head, forward cylinder line...I guess it is bad...The car is in good shape, runs well no sign of any problem and like it. Just I would ask for your opinion. What should I expect? Thanks Replies to this message: imidazol97 (Mar 11, 2009 6:01 am)

Replying to: vanderbar (Mar 11, 2009 5:05 am) I don't quit follow what you mean by under the cylinder head. I do know that valve covers do start leaking more with age. Do some cleaning and then rechecking with good lighting to see where the oil is coming from.   The valve covers are problematic as far as resealing. You might tighten lightly, but it's not going to cure it most likely. Removing, cleaning, new gaskets, probably are required.   You didn't happen to run synthetic oil in it? That often supposedly opens seeps and causes leaking.

imidazol97, I rechecked as you mentioned. It is not under the cylinder head, but from the inlet manifold itself. Hm. Plus, the two trans hoses going from the trans to the cooler, they seep/leak... I run it with mineral oil, no synthetic. Replies to this message: imidazol97 (Mar 11, 2009 2:36 pm)
