New To Group. Need Help With 85 W-150 RUST

From : stacker

Q: tom lawrence wrote would that also cause the vehicle to hesitate when first started not really... the sole purpose of the iac motor is to allow the engine to get enough air when the throttle plates are closed foot off the accelerator to maintain proper idle speed. if the engines idling fine the iac is working properly. it could be a bad tps throttle position sensor whos job is to monitor the position of the throttle plates. the pcm uses this to say ah hah the throttle plates are opening so i need to add more fuel adjust the timing all that fuel-injection stuff. the pcm uses the tps reading as sort of an early warning that the mixtures going to go lean rather than wait to sense a change in pressure within the manifold via the map sensor. try this next time... put it in gear give it a couple of seconds then let off the brake but dont give it any throttle. if the engine is still running smooth very gently and very slowly apply some throttle. if that keeps the engine running good but nailing the throttle from a stand-still causes it to hesitate then id go ahead and troubleshoot the tps with a voltmeter and if found to be bad replace it. thanks for the help. it gets worse the colder the outside temp. it doesnt do it much right now since its hot. .

dale all the late model cars use very light guage sheet steel to save weight. however all the sheet metal is coated at the factory before final paint. chips in the paint will not cause rust. simple touchup paint suffices. obviously any chips that deform the metal has the potential to damage the coating. this coating is also applied to the flooring panels as well. i think any holes drilled or punched anywhere on the vehicle is a risk and should not be done. the mudflaps on my 04 ctd are factory flaps and do not mount to the sheet metal. they have special fasteners that mount to the plastic polypropolene inner fenders. some of the responders have mentioned rhino liner and other similar products. yes they are very good but they add a lot of weight and they have the potential to create cavities that can collect water without detection because of poor bonding due to oil and grease not properly cleaned first. my comment about ford is only partially correct. i apologize. ford has no equivelent to the cummins. the power stroke isnt even in the same league. however i wasnt thinking about their gas engines. the ford v8s are much better that the dodge competition. maybe the hemi will prove itself but im not buying one yet. ok steve what would you put on your truc

craig@metronet.com wrote 18000.00 canadian dollars what is that 25.00 usd if so thats a pretty good deal. buy the ford. im just trying to lighten the mood. everyone gets so worked up about the dumbest shit. did you have any idea how explosive a discussion rust on your truck would be. go eagles! craig c. but if it happened on my truck i would be just as pissed as dale. especially if dc wont help him. i bought a 95 firebird convertible new and the dealership where i bought it promised to replace the optically distorted windshield. well they did but with one much worse. apprarently whoever supplied gm with windshields for the firebird back then had a serious quality control problem. the dealership refused to put another one in it. i then appealed to gm who told me they always support their dealers. so to make a long story short gm was forced to buy the car back. there were other problems with the car that gm wouldnt fix. i havent looked at another gm product since then. and i wont. why because of the way i was treated by the pontiac dealer and gm. and loking at gms sales and financial info i dont believe i was the only one. companies need to be held accountable for the actions of the dealers. after all the dealers are acting on behalf of these companies. bob go cowboys!! .
