Hi everyone im new to the site. and i own three 4runners years of 91,93,95 my 91 is in the shop for a new engine rebuild my 95 is a scrap car to fix anything that needs fixing on our 91 and 93 lol... Well i just got my 93 4runner out of the shop for a clutch kit and new pedal and so everything is running good on it but a week out of the shop my truck starts to run like crap. my power steering pump was broken or whatever and was running like crap, well got the power steering pump fixed and now my truck stops smoking (like it did when the pump was broken) and started to run fine. but now it is running like crap. when it starts from being cold it runs perfect but after it warms up it sounds boggy and just crap lol. so im wondering whats going on with it. why would it run like this. i know im not giving much of any detail but idk what to do. im afraid to drive it because i dont want it to blow up like my 91 did
