any ideas?? its on my moms 07 jeep grand cherokee. haven't actually looked into the problem yet, but I'm just trying to get some heads up of what to look for.
.Disconnect the throttle cable from the TB and check the linkage by hand to make sure the problem is not with the TB first. If the problem is there, remove and clean the TB. Hold the end of the throttle cable up and spray some WD40 down inside the cable housing. If none of this solves the problem, you may have a bad throttle cable and will need to replace it.
If it has the drive by wire setup, you're own your own with this one because I'm dumb as dirt when it come to that!!
.The first thing I would check is the Floor Mat, it sounds stupid but I have seen people spend hrs trying to diagnose to only find out the pdl was catching on the floor mat
.Whatever you do, get it fixed ASAP! you do NOT want to be tooling along and suddenly find yourself with it stuck at WOT! DAMHIK!
be prepared for that to happen anyway...practice your quot;emergency shutdown proceedure...slam it into neutral, hit the brakes and kill the ignition, but don't lock your steering wheel so you can still steer to the side of the road. you may find that with the engine RPMs sky high, you'll have to keep bumping the ignition as the RPMs fall, so that you can steer. if the RPMs climb to 4-5K, it'll take a good 3 seconds or so for it to spin back down, and if all you do is kill the ignition and turn it back right away to keep the wheel unlocked, it'll turn on all the relays, and it will re-fire the engine, but if you kill the ignition and leave it off till the motor stops turning, then you'll have 3 or 4 seconds of no steering.
both situations are NOT good!
so get that problem fixed BEFORE you tear something up! |
