yes I had the egr off and cleanned it up real good and even blew air through it with vac.pump pumped up and it let air pass through it. I do have another question that maybe someone may want to help with or give there .2 When I ran the sea foam through the car I sucked it through a vac line...

TedC I cant thank you enough for all your help.I think I am going to order a egr and give it a try.As for the carbon build up I aslo think you are right,just not sure how to go about that.I figure after I install the new egr I will try running a few tanks of good gas and see if that will help.I...

I did the vacum line into the car with the vac gauge today and Once car was up to temp it started reading when I gave it some gas it Moved around from 3-10 hg.So next just for the heck of it I wedged the egr partialy open and took it up the road.It still sounded like it was pinging.It didnt want...

Ok did some testing today and yes the egr will hold vac with car not running,but it takes like 10 in.hg just to crack it open and I cant get it to pump up any higher.I started the car and could not get it to hold any vac.I then put a mirror under it to see if it was opening and with me pumping...

tomorrow I plan on rechecking with a mirror to make sure it is unseating.I will report back with what i find.Just want to tell everyone thaks so much for all the input.

I have tried to open egr(unseat) at a idle and still got no change.I didnt get a chance to work on it today.I started to check the compression yesterday before i got called away due to a friends daughter blowing her toyota up.Anyway the two cyl that i did check where both 185-190 lbs.My car runs...

i drained the fuel already and filled it with 91 chevron and 1 bottle of 108 octane booster.then drove it for about 60 miles. that did very litle to help

yes it pings when cool or cold .I think it pings alitle more when hot.I tried to run some sea foam through it,but didnt seem to help.

no check engine light.It comes on during start up and with maf. unplugged it came on.I have checked for codes and got nothing.Pinging is at its worst at light throttle.

Most of the questions you are asking I cant answer,because I just got the car two weeks ago.Only thing I have found that is unstock is the flowmasters,and the hypertech air foil on the tpi.Timing is set at 6 degree btdc.And it has new injectors(so the past owner told me)And they look new.Now for...

Wow,I am at my ends with this.Today I got the car back together after pulling the tpi,runners,and egr off.I found that everything was full of carbon.So i pulled it all apart and cleaned it up real good.Then put it back together and ran some sea foam through it and replaced the spark plugs.Well...

I checked for codes and get nothing.I have checked for vacm leaks using carb cleaner,and again trying staring fluid.Both with no results.I did check the injectors and they all had 15.9-16.1 oms.So I guess that is good.I did notice that with the egr off it is ptetty tough to get it to open(takes...

How would i tell if they are the right injectors?I thing he had a chevy dealer do them.I pulled the egr off tonight.The tpi runners and body itself have lots of carbon.I tried to clean the intake port out where egr goes.Pulled out gobs of carbon.The egr looks new.It is a gm part number 17086078...

Have you checked for codes?Sounds like it may be a maf..Just my .2 I had a iroc z with same problem years ago and that was my problem.First thing to do is check for codes

Ping is more at a light acc.Than wot.I see the valve on the fuel rail,but do I need a special gauge to check fuel presure??I agree with you on the ks.It seems to not be working,but should not be neede everytime I step on the gas....I rechecked the injectors last night,even though they where said...
