Pull EGR valve anbd was nasty. Used oven cleaner to clean it, nasty nasty. That did the thick. On my last truck this would throw an engine code??

I'll try anything once............OK

Today.........cut exhaust to adjust the Cat........found it hollow gone. Put anti-flowler on O2 sensor, no more 420 code. No codes at all Cleaned MAF sensor with correct cleaner and put on a new air filter Checked all vacuum lines.......already replaces all of them Cap Rotor wires and plugs 15,000 a...

My 98 astro 150,000 miles auto has started Idling rough. If I turn a/c off nothing changes. If I drop it in netural she smoothes right out. If I give it just a gas a touch it smoothes out. No Codes showing. New fue l pump, did it before pump. Need a clue were to start. Runs and drives great.

Thanks

Well after screaming for 60,000 miles my fuel pump finally got real quiet. Right in a customers driveway at the first stop of the day with many more to go. I'm driving a caravan for a day and nobody better point and laught!!!!!!!!

This is not an answer about the airbag light. Just a suggestion. If you buy a scanner or just a code reader it will pay for itself the first time you need to use it. These days it can be the handiest tool in the box. \:D/ I have a normal scanner............thought it is still like a $1000 for the a...

My 98 Astro has to keep atlast one dash light on at all times...now its the air bag light. Anything I can do?
Dealer scan $89!!!!!!

Replaced valve body.......kinda easy once I found all 7 balls. I was shocked to find the pan so clean with just a teaspoon of gray stuff on the magnet. Now it locks up and shifts smooth...for now. Next project engine in a 99.

You don't want the TC unlocked all the time as it make huge amounts of heat while unlocked and will eventually toast the trans. In your 98, the TC locks in 3rd and 4th (OD) only. 1st and 2nd do not lock up. I'm gonna do my 1st shift kit / valve body Saturday.........if I'm not back in 3 days please...

Is there way to stop the TC from locking up. Most of my driving is high speed through city streets and the something just feels wrong. I ordered a rebuilt valve body with upgrades to fix the P1870 code. Its a 98 with 140,000 so far.

They are suppose to come with radio's and owners manuals.......I've been screwed again!!!!!!

BUT its a caravan and do you know why everybody wanted $1000 to replace a head gasket????? Because it is a rotten job

My wife thinks I should drop all my petty projects and finish the head gasket in the ^%$%^ caravan she had to have. I told her I would fix the astro and she could have that but nooooooooooooooo she dosen't want a truck????????? WHAT TRUCK????????????
Stupid scoocer mom wannabe

Hi..... I bought my 1st astro brand spanking new in 1988 and chevy bought it back from me after 12,000 miles. The only thing that did not break was the engine block itself. At 12,000 miles the transmission blew a hole in the case. They put a new trans in and it would not shift into 4th......Changed ...
