wash the engine now it's f**ked
yester day i washed my engine off after changing my coolant temp sensor, this was hopefully the last thing that needed to be changed to let the car idle down.
well after i finished it wouldn't start, so i let it sit all day with the hood up, so it would dry out, still nothing, so this morning i dryed the dist cap and coil off, and changed the oil because it was a little gassy from cranking it over so many times.
well it starts, and actually idles down, i'm happy :hurray:
i then go to take it for a test drive and it missing and farting, intermittantly, it will also let out huge backfires out thew exhaust, so big that my exhaust now sounds louder, i must have blown something out :confused:
and to top it all off, it is back idleing at 2000 rpm again, WTF would be causing this???
i'm pissed to say the least
:mad :mad :mad
can someone please help
thanks Greg

blast the opti with some shop air to clear out the crap in the optical diodes within the optispark. Make sure the connection on the water sensor doesn't have anti freeze trapped within the connector...

Well judging by your exhaust statement, maybe it was a coincidence that you had a clogged cat that finally fell apart while you were working under the hood, and when it popped, it was the chunks of honeycomb working loose and therefore giving you the louder exhaust.
Although one time me and my buddy were cruising through the pine barrens and he stalled in a giant mud puddle, when we got the truck started again, it backfired and cracked the distributor cap. Ran like crap, but we got home OK.

Re: wash the engine now it's f**ked (Mr Mojo)
i have no cats, straight exhaust to turbo mufflers :nonod:
the car will run fine at some rpms but when taking off or slowing down it backfires, stall or and runs like crap
i tried to take it for a highway run a while ago, but almost got run over by a pulp truck when it wouldn't get going

just incase any of you flat landers don't know what a pulp truck is, every week around here someone goes head on into one of these. onbody ever survives it. it's full of wood chips for making paper (wood pulp)

I killed my 87's TPS the other day washing my engine.
Check the trouble codes. If it has a 21 and 33, or just a 21, it's a bad TPS.

i just tried to take it around the block, i let it idle for about 1/2 hour, everything seemed perfect, i had just cleaned every connection on the engine with wd-40 to get the water out, i started goig around the block and it backfired so hard that my muffler exploded :eek: :yesnod:

Re: wash the engine now it's f**ked (atotalnincompoop)
When you washed your engine, moisture condensed inside the distributor cap. Running the engine with moisture inside the cap will cause sparks to jump everywhich way and fire plugs whose cylinder has an open intake valve and/or during valve overlap causing backfires. Replace the distributor cap and the rotor because of likely carbon tracking and leave the cap off for several hours so everything can dry out. Check out your MAF because backfiring through the intake can rip the hot wire air flow sensor out of the MAF.

not usre if you did this or not, but you want to cover the distributor with a plastic bag even for L98's to keep it dry when washing the engine

I have washed my engine twice and both times fried the TPS...both times it wouldn't start, and finally when it did, idle was thru the roof.

I'm sorry to hear of your recent troubles :sad:
Be honest...You always wanted Flowmasters anyways! :thumbs: Now's the time! I suggest the 40 series with rectangular LT1 style tips. They tuck right up, sound great and the tips fit the bumper bezels perfectly...got it all installed locally for less than the price of the mufflers alone from MAD. I'm knocking the stuffing outta the cat this weekend.
:rant:
I guess I'll try replacing the temp coolant sensor on mine and see if that helps with my surging idle. I've got the gaskets to pull the plenum and intake this weekend too. I have used the scanner to check the TPS voltages thru out it's range and I don't see the values jumping around. Hell, might replace it anyways...already have almost everything else...why break up the rally?
Now that I have the AC working great I've been using it alot more. Now the compressor is making noise...WILL IT EVER END?!
You didn't cross the wires did you? Did you pull them off the cap when you dried it and maybe .... ? :seeya
