    Seems I've tried about everything- running out of ideas-- truck seems to lack power- but catalytic is not plugged- backpressure gage says it's okay.

    2000 Astro van- multiple misfire codes keep coming back...

    So my buddy's van will run great for 2-3 months, then start throwing the PO300 code- and hesitation abounds.primarily when wet out, of course--but at times when dry. The answer has always been to change out the distributor cap (and rotor) and all is lovely for another few months- wires were...

    '99 S-10 2.2L engine R&R - Must I pull Tranny?

    So on to my next project, '99 S-10 2.2L 5 speed manual tranny- If it was an automatic tranny, I'd just leave it in there- done one like that already, but this is my first manual tranny- sure would save some time if I can loosen it but not pull it out...I'm going to try it-- but wondered if...

    Well, I'm on to my next project- this one is my own truck-- an old POS haybale hauler that I use everyday between farms to deliver a dozen bales of hay each day to the animals. Sure is hard to work on your own stuff- but he sun is out and it's above freezing, and a little slow here- so here...

    '98 Chevrolet K2500 Fuel Pump Inop....low Pressure 5.7L engine

    So the truck is towed to me- owner says it runs on carb cleaner then dies--I run my checks-- fuel pump (through primer circuit) pulls only 1.67 amps and generates only 13 psi pressure- not nearly enough to start. I usually don't see this failure mode- I can hear pump run- but why such low...

    99 Yukon - 5.7L - Runs 30 mph without pushing Accelerator

    So what gives? With Tech II attached IAC is same as desired- at all speeds, idle, driving, whatever. The desired idle while driving is always half of actual engine rpm- with no brake or accelerator applied and in gear- result is 30-40 mph . If you stop completely, and in gear, desired idle...

    '95 Geo Prizm - What Coolant?

    I'm installing a salvage yard engine (old one blow a rod through the block) in a '95 Geo Prizm- the old coolant looks reddish- much like Dexcool- but I know this is a GM/Toyota joint venture car- and they may not use the Dexcool-- besides, I thought GM started using Dexcool in '96 model year...

    2005 Chevy Malibu spongy brakes after new pads front and back

    My neighbor calls me- brings his 2005 Malibu over- he had changed all brake pads (all disc brakes). The brake pedal goes clear to the floor- but you can pump it several times to get it firmer- and the brakes will all eventually work. He had bled all four wheels- fearing he had gotten air into...

    So two months ago I put a new fuel pump in my buddy's 96 Bonny- now when gas tank is low- on long exit/entrance ramps- the fuel gauge goes to empty- alert dings and the engine will soon stall out. Car starts right back up once leveled out. So the question is- what changed- did I miss something...

    Fuel Pump Relay Location - 96 Bonny- Vin "K"

    My Mitchell-on-Demand steps all around it- but won't describe where it is at- I believe it is under the passenger side footwell- on that I/P fuse box- There are clicks on and off after ignition is on for 2 seconds- so it must be the relay- but I removed each one at a time- and clicking was still...

    This car is kicking my butt--- It will run and idle for about 12-15 minutes- then go into a chuggle and near stall-- several times then finally stall-- after each recovery the engine purrs fine- just every so often- times vary- it will just take a dive and sometimes stall.. I have replaced the...

    Since its cold- I have been helping my buddy out- he can't get adequate heat out of his heater- air flow has good volume- temp door works- I flushed out heater core by plumbing a water line through it- flow seems as good as can be expected- so I am certain it is not plugged or restricted- So...
