Low idle and running rich

Well if the blown head gasket is filling the cylinders with antifreeze that could cause it to stall out too. I just did the head gasket on my 88 7MGTE and it wasn't hissing, thats more likely a vaccume leak, but if the car sat for a while the antifreeze would seep into the oil pan and it would run fine for a while but after running for a while it would start runnning rough and then die out. At ope throttle it would run fine because the engine was exhausting the antifreeze faster than it was drawn in. If your leak isn't a very big leak then that could very well be the case. Mine on the other hand, I put a new head gasket on mine and never had the head checked. My mistake, I had to do it twice and have the head machine at a local shop here because after checking my head I foud it was warped. The machine shop had to take two thousanths of an inch off mine to fix it. Well let me know what you find.

Thats probably the case. the guy said it had a blown head, and it seems to act like it. Its fine when the engine is cold, and then after warming up, it starts to die out, and is hard to get up to speed. it kinda goes in and out of accelerating and stuttering, like its trying to die.

a while ago it was idling really rough, kinda clunking a bit and idling at 500-600, and would rev like....slow...going WOT when its just warming up, like...5 minutes after driving seems to have no affect on the power or speed.

Anyways...I found a link to buying a HG set... 7MGE Toyota Head Gasket Set (86-93) from PartsDinosaur.com..I know its cheap, but please understand, I cannot afford to do everything right now. The jackass I bought my 89 from hid every last thing from me until after the engine was running and was able to stretch its legs. At that time, that "Stop Leak" crap he put in there blew through the head, the crap in the heater core was forced out, and massive amount of coolant went into the engine and that cost 1200 bucks. plus the set was like single gasket was just for the top and I was charged 150 for that. I got new struts and that was about 540. new tires was about 520. I had about 5500 dollars to make this work, but insurance hit hard, so now im down to my last reserves of 100 bucks. I just got this 86 for 500 bucks, and it needs some minor things it seems like. at least minor compared to what went into the other one.

Anyone know how to take struts off the car...lol, kinda thinking on selling it, and salvaging what I can...lol
