Mew wires,cap,and rotor.It still runs like crap at idle and blows smoke back up through the engine. If I leave the oiler filler cap on it builds up a pretty good amount of pressure until I release it. I am stumped! Could the cat be plugged? What else could be causing so much back pressure??? <img src="/forums/images/graemlins/confused.gif" alt="" /> <img src="/forums/images/graemlins/confused.gif" alt="" /> 2002 XLS /LSD/Thule Rack /PIAA Extreme White headlamps /K+N system/Michelin LTX MS--KYB gas-adjust all around 95 LS-- Dual Bouncy Seats 234k and still rockin' Re: Still having problems with engine pressure in my 93..HELP!

It will start up with a decent ammt of hg and then vac gauge will drop down. Or unbolt the cat on the manifold side and go for a loud ride. Now doing a compression test is the easiest way to check for bad rings, valve seats, or a hole if you are that unfortunate. Bottom line is you can test all this yourself with < $50 of gauges. 89 v6 Raider 5spd 89 v6 Montero auto 86 TD Trooper Moderated by  4x4Wire, Macka, Mudraider, off-roader, PHIL_, rxinhed  Hop To Mitsubishi Forums ------  Mitsubishi 4x4 and SUV Tech  Mitsubishi Diesels  Mitsubishi ArchiveToyota Forums ------  Early Toyota Trucks  Toyota 4Runner, FJ Cruiser &...  T100 & Tundra Forum  Tacoma Forum  Toyota Tech ArchiveJeep Forums ------  Jeep Talk  Jeep TechIsuzu Forums ------  Isuzu 4x4 & SUV Talk  Isuzu 4x4 & SUV Tech  Isuzu DieselsKia Forums ------  Kia Talk  Kia Sportage & Sorento TechOff Topic Chat ------  4x4 Gallery  Off-Topic Chat  Recreational Access & Land ...  Politics4xForums ------  Outdoor Gear  General 4x4 Discussion  Tools and Fabrication  General Communications  Amateur Radio  GPS and MapsParts Bin ------  Private Party - Garage Sale  Private Party - Items wanted  Vendors, Hot Deals, Group Buys4x4Wire Back Yard ------  Suzuki Forum  AZ Crawler Crew  Cal-Nev Crew  General Ford 4x4 & SUV Forum  General Dodge 4x4 & SUV Forum  General Chevy 4x4 & SUV ForumFeedback & Testing ------  Problems, Questions, Suggestions4x4Wire Staff ------  Forum Moderators  Problem Threads Print Thread Switch to Threaded Mode 5 Excellent 4 Good 3 Average 2 Bad 1 Terrible View Profile Private Message Follow User Forum Posts View Profile Private Message Homepage Follow User Forum Posts View Profile Private Message Follow User Forum Posts View Profile Private Message Follow User Forum Posts
