Kenny Lee posted a topic in Cadillac Deville, Eldorado, Seville, Fleetwood, Sixty Special2002 Seville SLS with 220,000 miles. Good starting and idlling, but I try to accelate it, it never goes over 2,000 rpm. And not more than 20 seconds it drops down to 500 rpm automatically or stops with trembling. My struggles for..... 1. replace fuel pump and fuel filter. 2. replace secondary air injection hose assembly (none when I buy my car) 3. cleaning and checking eletronic EGR valve, and it works smoothly. 4. checking and cleaning Mass Air Flow sensor. It is clean. 5. cleaning air intake cabulator with cleaning spray and soft cloth. There was a lot of carbon. 6. There was 'check engine soon' sign, so checking my Caddy's Info Center. there is P0403 code only. 7. After I deleted all codes in Info Cenetr, 'Check engine' sign has gone. 8. No bubbling in coolant reservoir. Excess high temperature in cooling system I guess. But Temp. guage is in normal. 9. Still I can hear the noisy sound and some smoke in bumper area of driver side when I accelate. (I am doubt of abnormal secondary air injection pump.) 10. Anyway......2,000 rpm limitation exists. What should I do next?
I just brought a '97 D'elegance yesterday for $1,000 in Maryland. It overheats almost immediately. Every time I drive it the temperature shoots up pretty fast around 244F in about 5-10 minutes or so. What did I get myself into? I think I got got. Oh well. What are some fixes? I dumped $135, for a battery, $240 for MDTags, $10 for tool kit to put in battery and tags, $ 368 for 1st and last months insurance. As well as the $1,000 for the car. I'm felling stubborn. I want to make it work. I refuse to just have wasted almost $2,000 in less than 24hrs!
